AB  - In this work, the dissolution behavior of a polyphosphate glass, with the composition 45P(2)O(5) center dot 3SiO(2) center dot 25K(2)O center dot 15CaO center dot 10MgO center dot ZnO center dot MnO (mol %), in simulated body fluid (SBF) at a temperature of 37 degrees C for different times was studied. Two powder sizes of the glass (granulation: 0.1-0.3 and 0.3-0.65 mm) and the bulk glass were investigated. The dissolution experiments were conducted under stationary conditions. Changes in the normalized mass release, normalized concentration of ions, pH values, and surface morphology were determined as a function of the dissolution time. The initial rates of glass powder dissolution and leaching of ions, as well as the diffusion coefficient of cations and the releasing rate of ions, during the hydrolysis process of glass were determined. It was shown that the investigated phosphate glass dissolves in SBF incongruently, with neither precipitation nor the formation of newly potentially toxic compounds, in a dissolution period 720 h.

AB  - Melt-quenching method was employed for obtaining a glass-ceramic with the following composition 42P(2)O(5). 40CaO.5SrO.10Na(2)O.3TiO(2) (mol%) glass. The crystallization and sintering behavior of glass have been studied by using DTA, HSM, XRD, FTIR and SEM methods. It was determined that the surface and volume crystallization mechanisms act simultaneously in bulk glass samples. The comparison of DTA and HSM data revealed that the sintering and crystallization processes are independent. The sintered calcium phosphate glass ceramic which contained bioactive beta-Ca-3(PO4)(2) and beta-Ca2P2O7 phases was successfully prepared. It was determined that during crystallization the primary phase in the precipitate was beta-Ca(PO3)(2). Other phases appearing in the resulting glass-ceramic were: alpha-Ca2P2O7, gamma-Ca2PO7, Ca4P6O19 and CaHPO4(H2O)(2). Crystalline phases containing Sr and Ti were not detected. SEM analysis of the glass-ceramic microstructure revealed surface crystallization of glass particles and plate-like morphology of crystal growth. The result of the in vitro bioactivity showed that no apatite layer was formed on the surface of the as-prepared glass-ceramic samples after immersion in the simulated body fluid (SBF).

AB  - The crystallization and sintering behaviors of polyphosphate glass doped with trace elements Zn and Mn were examined. The heating experiments on bulk and powder glass samples were performed. The parent glass revealed low crystallization ability and the glass crystallization carried out under simultaneous acting of the surface and volume mechanisms. The bulk glass sample isothermally heated at T (c) = 500 A degrees C commences to crystallize after 12 h, and KPO3 and Ca2KP3O10 crystalline phases appeared. The dendritic morphology of the crystals growing on sample surface was determined. The DTA and HSM results showed that the sintering and crystallization processes are independent. Phosphate glass-ceramics containing KPO3, K2Mg(PO3)(4), Ca(PO3)(2) and KCa(PO3)(3) crystalline phases has been prepared by sintering of the glass powder compacts at T (c) = 500 A degrees C for t = 12 h. A plate-like morphology of crystals which grow on glass grains surface was observed. The activation energies of crystal growth, E (a,k) = (246.6 +/- A 19.74) kJ mol(-1) (Kissinger) and E (a,oz) = (258.80 +/- A 19.70) kJ mol(-1) (Ozawa), were calculated.

AB  - The selected lanthanum-strontium borate glasses were prepared by a conventional melt-quenching technique. The compositions of the investigated glasses were chosen to be: 5.7, 9.5, 14.3, 19.1 mol% for La2O3, 22.9, 19.1, 14.3, 9.5 mol% for SrO and 71.4 mol% for B2O3. The density, molar volume, oxygen molar volume, oxygen packing density, oxygen/boron ratios and structural transformations in the glass network were investigated according to the substitution of SrO by La2O3. The density and the molar volume increased in parallel with La2O3 content increase. Simultaneously, oxygen molar volume values increased while the oxygen packing density values decreased. A hot stage microscope (HSM) and a differential thermal analysis (DTA) were used to determine the characteristic temperatures. By increasing the content of lanthanum, the glass transition temperatures, changed with the same trend as the molar volume. Glass stability parameters were calculated from the temperatures obtained by DTA and HSM. The HSM results were used to obtain the viscosity curves by applying the Vogel-Fulcher-Tamman (VFT) equation.

The parent glass was prepared by the standard melt quenching method, and the investigations were performed under non-isothermal and isothermal conditions using the DTA, XRD, SEM and EDS methods. The results revealed primary crystallization of this glass and the dendritic morphology of crystal growth. Three crystalline phases were formed in the glass matrix during crystallization, whereby LiNbO3 was formed as the primary phase, followed by Li2Si2O5 and SiO2 as the secondary. The surface and volume mechanisms of crystallization occur. The condition that both the mechanisms were dominant was determined. In the case of volume crystallization, the characteristics of the nucleation process were examined. The kinetic parameters of crystallization under different mechanisms of crystallization were determined.

AB  - In this paper the results of investigation of the polyphosphate glasses dissolution in acid solution at temperatures of 20, 30 and 37 °C were presented. The dissolution process in citric acid is complex and can be explained by hydration reaction and hydrolysis, leading to the disruption of phosphate chains which form the structure of glass. Mechanism of chemical reactivity of polyphosphate glasses, acting as slow release fertilizers in soil solutions was presented.  The results of the dissolution experiments indicated that this glass can be used as an eco- fertilizer in soil remediation.

AB  - In this paper the results of examination of the dissolution process of the polyphosphate glass 45P2O5×25K2O×15CaO×10MgO×3SiO2×ZnO×MnO [mol%] in 2% citric acid at temperatures of 15, 20 and 30 ºC were presented. The dissolution experiments were performed on glass powder grain size of 0.1-0.3 mm and 0.3-0.65 mm. The mass loss of glass, normalized concentration of PO43+ and K+ ions and the conductivity of solution (χ) as a function of leaching time was determined. It was revealed that for short reaction times, the changes of normalized mass loss (fm) are linear with time and the rates of glass dissolution under given conditions are highest. By increasing the dissolution time the dissolution rate of glass decreased. The initial release rates r0 (PO43-) = 3.550 [g/m2h] and r0 (K+) = 2.133 [g/m2h] at t = 300C were calculated for glass powder sample 0.3-0.65mm. The dissolution process in citric acid is complex and can be explained by hydration reaction and hydrolysis, leading to the disruption of phosphate chains which form the structure of glass.

AB  - Glasses with a constant B2O3 and an increasing La2O3 content in the system La2O3-SrO-B2O3 were obtained by the usual melt quenching procedure. The crystallization and sinterability of the glasses were investigated by hot stage microscopy (HSM), differential thermal analysis (DTA), X-ray diffraction (XRD) analysis, transmission electron microscopy (TEM) and scanning electron microscopy (SEM). XRD analysis of the bulk samples evidenced the formation of the crystalline phases: La2SrB10O19, SrB6O10 and SrLaBO4. XRD and TEM/SAED analyses showed a polymorphic crystallization of the glass sample containing 14.3 mol% La2O3 with precipitation of the La2SrB10O19 phase. SEM analysis confirmed the surface crystallization mechanism of this sample. The kinetics of crystallization of the same sample was examined by DTA and the activation energy of crystal growth was calculated by the Kissinger model to be E-a=458 +/- 63 kJ mol(-1).

AB  - Potassium germanate glass with molar ratio [GeO2]/[K2O] = 1.2 and Nb2O5 content of 34 mol% have been synthesized by a melt-quenching method. The crystallization behavior under non-isothermal and isothermal crystallization conditions was investigated. The results showed that this glass exposed complex primary crystallization. In the temperature range  LT  800 degrees C primary phase is K3.8Nb5Ge3O20.4, while K6Nb6Ge4O26 appeared as primary phase at temperatures > 800 degrees C. K10Nb22Ge4O68 and metastable KNbO3 and K4Nb6O17 were formed as secondary phases. The crystallization commenced at T > 640 degrees C with high homogeneous nucleation rate and spherulite crystal growth morphology. DTA curves recorded for powder samples particle size  LT  0.1 mm revealed three exothermic peaks and three endothermic peaks within temperature range of T = 640-940 degrees C, while the DTA curves recorded for powder samples particle size > 0.1 mm showed two exothermic peaks and two endothermic peaks within temperature range of T = 640-1020 degrees C. The analysis of the dominant crystallization mechanism of powder glass sample and kinetics of crystallization is presented.

XRD and SEM methods were employed for determination of phase composition and microstructure of crystallized glass. It was detected that this glass crystallizes by the surface crystallization mechanism. SEM micrographs of the crystallized samples revealed that the crystals grow in the form of dendrites. The glass-ceramics with complex phase composition was obtained. Three crystalline phases were detected where LiNbO3 has grown as primary phase and a secondary ones Li2Si2O5 and SiO2 appeared. The calculated average crystallite sizes are: 27 nm for LiNbO3 , 115 nm for Li2Si2O5 and 45 nm for SiO2 . From the experimental data an activation energy of crystals growth, calculated using the Kissinger relation, is Ea = 275 ±10 KJ / mol.

AB  - Ispitan je uticaj sadržaja K2O na kristalizaciju niobijum germanatnih stakala sa 22,7-24,27 mas % GeO2 i 54,59-57,48 mas % Nb2O5. Ova stakla kristališu primarnom kristalizacijom i stvaraju se kristalne faze K6Nb6Ge4O26, K3.8Nb5Ge3O20.4 i KNbO3. Povećanje sadržaja K2O prouzrokuje smanjenje sadržaja GeO2 u primarnim fazama. Analiziran je uticaj sadržaja K2O na kinetiku primarne kristalizacije. Pokazano je da povećanje sadržaja K2O smanjuje energiju aktivacije rasta kristala na prvom kristalizacionom piku (Ec1). Na drugom kristalizacionom piku energije aktivacije rasta kristala se povećavaju (Ec2).
AB  - The effect of K2O content on the crystallization of niobium germanate glasses with 22.7- 24.27 wt% of GeO2 and 54.59-57.48 wt% of Nb2O5 was examined. The glasses crystallize by primary crystallization and the formed crystalline phases were K6Nb6Ge4O26, K3.8Nb5Ge3O20.4 and KNbO3. Increasing the K2O content caused a decrease in the GeO2 content of the primary phases. The effect of the K2O content on the kinetics of primary crystallization was analyzed. It was demonstrated that an increase of the K2O content decreased the activation energy of crystal growth at first of the crystallization peaks (Ec1). At second crystallization peaks the activation energies of crystal growth increased (Ec2).

AB  - The nucleation of germanate K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal conditions was studied by the DTA method. The temperature ranges of nucleation and crystal growth of this glass partly overlap. The influence of the mass of the glass sample as well as, the time and temperature of the pre-DTA heat treatment on the DTA parameters T-p, (delta T)(p), and Delta T-p was investigated. A complex behavior of these parameters was evidenced. It was shown that for fixed temperatures, increasing the annealing time of the pre-DTA heat treatment resulted in a decrease in the temperature of the DTA peak (T-p). The curve of the dependence of DTA peak heights (delta T)(p) on time showed a maximum and the parameter Delta T-p continually increased with increasing time. The influence of the temperature of the pre-DTA heat treatment on the DTA parameters showed that for annealing times t>t(ind), the dependences of T-p(-1) and Delta T-p vs. T corresponded to the dependence of Ion Tin the case when the regions of I and U partly overlapped. As shown, in this case. the change of (delta T)(p) vs. T is not convenient for an analysis of the nucleation behavior of the glass.

The nucleation range is in the temperature interval 540-630 degrees C. A maximum of the steady state nucleation rate of I-max = 1.4 x 10(15) m(-3).s(-1) was determined at the temperature T-n(max) = 582 degrees C. The temperature and time dependence of the nucleation rate was analyzed and it was shown that such a nucleation behavior was the result of a low thermodynamic and kinetic barrier. The results showed that the temperature intervals of nucleation and crystal growth of this undercooled melt partly overlapped.

AB  - This paper presents the results of a study of the primary crystallization of a multicomponent mixed anion silicate glass. The primary phase, leucite, and the secondary phase, diopside, were formed by surface crystallization, while the secondary phase, phlogopite, was formed by volume crystallization. The influence of the particle size of glass powder samples in the range 0-1 mm on the temperature of the DTA crystallization peak, T-p, the height of the peak, (delta T)(p), and the parameter T-p(2)/(Delta T)(p) was studied. The behaviors of the parameters (delta T)(p) and T-p(2)/(Delta T)(p). depend only on the change in the surface-to-volume nuclei ratio, as is the P case with polymorphic crystallization. However, the particle size ranges in which the surface, volume and mixed crystallization mechanism dominate are considerably narrower for this glass. The influence of the duration of a pre-DTA heat treatment on the parameters T-p, (delta T)(p), and Delta T-p for fixed temperatures in the range T = 550-750 degrees C was investigated. The T-p of the samples thermally treated for different times, at fixed temperatures, decreased up to t = 5 h and then increased to a value close to that of an as-quenched sample, after which the value remained constant. The curves of (delta T)(p), and Delta T-p as a function of time for fixed temperatures show a maximum. The influence of the temperature of the pre-DTA heat treatment on the parameters T-p (delta T)(p), and Delta T-p, for fixed times of t = 1-5 h was also investigated. On increasing the pre-DTA heat treatment time, the curves changed significantly. The curves for 3 and 5 h in the temperature range 580-660 degrees C were similar to the nucleation curve, which indicated that the volume nucleation process proceeded in this temperature range. The behavior of these parameters, as a result of the simultaneous action of different nucleation mechanisms and crystal growth differ from those previously reported for the case of polymorphic crystallization.

AB  - U ovom radu su dati rezultati ispitivanja mogućnosti dobijanja alkalno aktiviranog bentonita za primenu u livačkoj industriji i za isplake kod naftnih bušotina. Ispitivanja su rađena na bentonitskoj glini koja se eksploatiše u ležištu Sokolac kod Šipova u Republici Srpskoj. Izvršena je kompletna karakterizacija bentonitske gline na uzorku uzetom iz otvorenog površinskog kopa ovog ležišta. Izvršena su laboratorijska tehnološka ispitivanja mogućnosti alkalne aktivacije na ovoj bentonitskoj glini dodavanjem natrijum karbonata kao ativatora. Na osnovu dobijenih rezultata fizičko-hemijske karakterizacije rovnih uzoraka bentonita, kao i tehnoloških ispitivanja alkalno aktiviranog uzorka bentonita, može se zaključiti da su optimalni rezultati aktivacije postignuti pri sadržaju sode od 4 mas %, te da dobijeni parametri kvaliteta ispitivani po standardima za primenu u livnicama (JUS.B.F.8.040) i isplakama (API 13A i OCMA DFCP-4) pokazuju da se dobija visokokvalitetan alkalno aktivirani bentonit koji ima primenu kako u livnicama za izradu kalupa tako i za isplake na naftnim bušotinama.
AB  - In this work the investigation results of obtaining of alkali activated bentonite for application in foundry and oil drilling were presented. The bentonite clay from the deposit "Sokolac" - Republic of Srbska was used for investigation. The detailed characterization of clay sample supplied from the open pit was employed. The laboratory technological experiments of bentonite alkali activation were performed by soda ash as activator.Based on the results of physical and technological characterization of raw bentonite samples and alkali activated ones, the optimal results of activation were obtained with soda ash content of 4 wt %. The quality parameters determined by using the specifications for foundry (JUS.B.F.8.040), and oil drilling bentonite (API 13A and OCMA DFCP-4), have shown that the high quality alkali activated bentonite was obtained for such application.

Rezultati pokazuju da se pri povećanju sadržaja anjona F- do 1,5 mol.% odvija homogena nukleacija faza i formira sitnozrna kristalna struktura sa povećanjem sadržaja slojevitih silikata. U oblasti sadržaja anjona F- od 1,5 do 2,0 mol.% odvija se heterogena nukleacija faza, opada sposobnost rastopa da formira staklo, nastaje krupnozrna kristalna struktura i dalje raste sadržaj slojevitih silikata. Povećanje sadržaja anjona F- ne utiče na mehanizam kristalizacije stakala.

In the F- anion content range of 1.5-2.0 mol%, the heterogenous nucleation of the phases occured, the melt glassforming ability decreased, the coarse grain crystal structure was formed and the contentlayered silicates were increased. The crystallization mechanism of the glasses dofes not change if the F- anion content is not increasing.
