AB  - Due to pozzolanic characteristics, fly ash is commonly used as a cement replacement in construction composites. Addition of natural clays with sorption ability (i.e. zeolite and bentonite) in to the fly ash based construction materials is of both scientific and industrial interest. Namely, due to the application of sorptive clay minerals, it is possible to immobilize toxic heavy metals from the composite structure. The thermal compatibility of fly ash and zeolite, as well as fly ash and bentonite, within the composite was observed during sintering procedure. The starting components were used in 1: 1 ratio and they were applied without additional mechanical treatment. The used compaction pressure for the tablets was 2 t.cm(-2). The sintering process was conducted at 1000 degrees C and 1200 degrees C for two hours in the air atmosphere. The mineralogical phase composition of the non-treated and sintered samples was analyzed using X-ray diffraction method. Scanning electron microscopy was applied in the analysis of the microstructure of starting and sintered samples. The thermal behavior was observed via DTA method. The influence of temperature on the properties of fly ash-zeolite and fly ash-bentonite composites was investigated.

AB  - Since cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2) (MAS), is a very useful high-temperature ceramic material, it is important to decrease its sintering temperature. In order to accelerate the process of sintering, 5.00 mass% MoO3 was added to the starting mixtures. The mechanical activation of the starting mixtures was performed in a high-energy ball mill in time intervals from 0 to 160 min. After the activation, starting mixtures were sintered at 1300 A degrees C for 2 h. In order to determine the impact of mechanical activation on particle size distribution and powders morphology, the mechanically treated powders were characterized by a laser light-scattering particle size analyzer and scanning electron microscopy. The phase composition of the starting mixtures and sintered samples was analyzed by the X-ray diffraction method. In order to determine temperature intervals of chemical reactions and phase transitions, differential thermal analyses (DTA) and thermo-gravimetric analysis were used. Kissinger's equation was employed to calculate apparent activation energies of various processes that occur within the system during heating. Based on the obtained DTA results, it was established that mechanical activation along with MoO3 additive has influence on sintering temperature which was decreased for more than 100 A degrees C, comparing to the literature data.

AB  - Calcium phosphate coatings were electrochemically deposited on titanium from an aqueous solution of Ca(NO3)(2) and NH4H2PO4 at a current density of 10 mA cm(-2) for a deposition time of 15 mm. The obtained brushite coatings (CaHPO4 center dot 2H(2)O), were converted to hydroxyapatite (HA) by soaking in simulated body fluid (SBF) for 2, 7 and 14 days. The brushite and hydroxyapatite coatings were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). It was shown that increasing the soaking time increased the porosity, roughness and crystallite domain size of the HA coatings and decreased the unit cell parameters and unit cell volume, while the mean pore area of HA was unaffected. The calcium and phosphorus ions concentrations in SBF were determined by atomic absorption spectroscopy (AAS) and UV-Vis spectroscopy, respectively, and a mechanism of HA growth based on dissolution-precipitation was proposed.

AB  - Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400 degrees C). Because a low temperature process is desirable, it is necessary to find functional ads which can allow easier sintering process at lower temperature. The influence of MoO3 on the preparation process of cordierite ceramics was investigated. 2MgO-2Al(2)O(3)-5SiO(2) was researched by sintering followed binary systems: MgO/MoO3, Al2O3/MoO3 and SiO2/MoO3 (all sintered at 850 degrees C and 1100 degrees C, sintering time 2h). Composition of these systems was 80 mass% of oxide and 20 mass% MoO3. The effects of sintering, the composition and morphology were followed by X-ray diffraction and SEM microscopy. It has been found that MoO3, beside liquid phase, forms intermediary unstable compounds with MgO and Al2O3, which is the significance information for further research. MAS ceramics were sintered with 20 mass% MoO3 at 1100 degrees C, 1200 degrees C and 1300 degrees C, during 2h.

AB  - Due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a very attractive high-temperature ceramic material. In order to accelerate the process of sintering, 2.50 mass% Bi2O3 has been added to the starting mixtures. Liquid phase sintering caused by the presence of bismuth-oxide lowers the temperature of cordierite formation. The mechanical activation of the starting mixtures (0-56 min in vibro-mill) additionally lowers sintering temperatures. The sintering process was performed at 1200, 1300, 1350 and 1400 degrees C, for 2 h. The particle size analysis (PSA) was employed in order to determine the changes in the particle size of the mechanically treated powders. The phase composition of the starting powders and sintered materials was analyzed by the X-ray diffraction method. Furthermore, scanning electron microscopy (SEM) was used in the analysis of the powder morphology.

AB  - Electrochemical deposition of calcium phosphate coatings on titanium was performed galvanostatically from the aqueous solution of Ca(NO3)(2) and NH4H2PO4 with the current densities between 5.0 and 10 mA cm(-2), for different deposition times, at room temperature. The coatings were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results showed that dicalcium phosphate dihydrate (DCPD), brushite (CaHPO4 center dot 2H(2)O) coatings were deposited. The influence of applied current density and the deposition time on the phase composition, crystallite domain size and the morphology of brushite coatings were investigated. It was shown that brushite coating of the greatest mass was obtained for the longest deposition time, while the increase in current density over 7 mA cm(-2) does not affect significantly the mass of brushite coatings. The finest crystallites, with the smallest crystallite domain size of 15.6nm, were deposited at the current density of 9.0 mA cm(-2). Brushite coatings were fully converted to hydroxyapatite in simulated body fluid (SBF) which was confirmed by XRD and SEM. The crystallite domain size of HA coatings is controlled by applied current density for brushite coatings deposition: crystallization of HA at more porous brushite coatings, deposited at higher current density, caused the formation of smaller crystallites of hydroxyapatite.

The synthesized monetite powder was characterized by X-ray diffraction, infrared spectroscopy, size distribution measurements, thermogravimetric and differential thermal analysis and scanning electron microscopy. Monetite powder was electrophoretically deposited on titanium from ethanol Suspension, using constant voltage method. The deposition was performed at constant voltage between 10 and 50 V and for a constant deposition time between 1 and 30 min. The influence of the applied voltage and deposition time on the mass and morphology of monetite deposits was investigated. It was shown that monetite deposits of the highest thickness and the lowest porosity can be formed at lower applied voltage (30 V) and for longer deposition time (20 min) and then converted to hydroxyapatite.

AB  - Surface modification of hydroxyapatite (HA) thin films electrodeposited on titanium was conducted by ion implantation, using nitrogen and argon ions at different constant fluences of 1x10(15), 1x10(16) and 1x10(17) ions/cm(2). SEM and XRD analysis, as well as SRIM calculation, were used to monitor the changes induced by ion bombardment. In the case of HA film implanted with N4+ ions, the unit cell parameters and unit cell volume increase with increasing nitrogen ion fluences. Similarly, the unit cell parameters and unit cell volume increase after Ar6+ ions irradiation to a 1x10(15) ions/cm(2). At higher fluences, the unit cell parameters and unit cell volume decrease when argon ion fluences increase to 1x10(16) and 1x10(17) ions/cm(2). These structural changes are consequence of different mechanism of energy transfer of nitrogen and argon ions to HA film. For nitrogen ion irradiation electron energy loss is predominant, while for argon ion irradiation nuclear energy transfer to HA film prevails.
