AB  - Cordierite (2MgO·2Al2O3·5SiO2) as a ceramic material has great importance in materials science and wide application in industry thanks to its low thermal expansion and dielectric constant, high chemical and thermal stability and high electrical resistivity. Cordierite ceramics is used for producing supports for electric heaters, ceramic fire resistant materials for furnaces, catalyst supports for the complete combustion of exhaust gases of internal combustion engines, insulation material in high frequency electronics, as well as substrates for integrated circuits and electronic modules. Properties of sintered cordierite ceramics, where cordierite powders were obtained by alkoxide hydrolitic and non-hydrolitic method, colloidal method and starting from silicic acid, were studied and compared. The properties of sintered materials were observed by SEM of the fracture surfaces and polished and thermally etched samples. The mechanical properties of obtained materials, microhardness and indentation fracture toughness, were determined by microindentation method. The best sinterability showed powder obtained by colloidal method (sintering temperature of 1370 °C for 2 h), and powder obtained by Si-acid method (sintering temperature of 1400 °C for 2h).

AB  - Hidroksiapatit se široko koristi kao keramički biomaterijal zbog svoje bioaktivnosti koju ispoljava kada se u vidu prevlake nanese na metalni implantat, kao i zbog kompatibilnosti sa sastavom ljudskih kostiju. Prevlake hidroksiapatitnog nano-praha elektroforetski su istaložene na peskiranu površinu uzoraka od nerđajućeg 316LVM čelika, pri konstantnom naponu i za različito vreme taloženja, a potom sinterovane u vakuumu na 1040°C i u atmosferi argona na 1000°C. Premda visoke temperature sinterovanja, koje su neophodne kako bi se dobile kompaktne prevlake velike gustine, mogu da dovedu do faznih promena kod hidroksiapatita, u ovom radu je pokazano da je na supsrtatu od 316LVM čelika moguće dobiti bioaktivne prevlake u kojima nije došlo do fazne promene zahvaljujući prirodi korišćenog hidroskiapatitnog nano-praha stehiometrijskog sastava. Visokotemperaturna stabilnost korišćenog HAp praha potvrđena je DTA-TG analizom u temperaturnom opsegu 23-1000°C, tj. na temperaturama na kojima su rađeni eksperimenti sinterovanja. Mikrostrukturna karakterizacija nanetih prevlaka urađena je korišćenjem SEM, dok je za određivanje faznog sastava korišćena XRD analiza.
AB  - Hydroxyapatite is a widely used bioceramic material in implant coatings research because of its bioactive behavior when being deposited onto the metallic implant and compatibility with the human bones composition. The coating of nanosized hydroxyapatite was electrophoretically deposited on a blasted surface of stainless steel 316LVM samples at constant voltage, for different deposition times and subsequently sintered in both, vacuum and argon atmosphere, at 1040 and 1000°C, respectively. Although sintering temperatures needed to achieve highly dense coatings can cause HAp coating phase changes, the possibility to obtain a bioactive coating on 316LVM substrate, without the coatings phase changes due to the nature of the used stoichiometric nanostructured hydroxyapatite is presented in this work. The thermal stability of the used HAp powder was assessed by DTA-TG analyses over the temperature range of 23-1000°C, i.e., at the or nearby experimental sintering temperature. The microstructure characterization was accomplished using SEM, while phase composition was determined using XRD.

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.

AB  - Boehmite aqueous sol was prepared by the peptization of Al(OH)(3). The solid phase, obtained by drying the prepared aqueous sol, was characterized by infrared spectroscopy and X-ray diffraction (pseudoboehmite was confirmed), thermogaravimetric analysis (the water content in the pseudoboehmite solid phase and the starting formula of pseudoboehmite, Al2O3 center dot 1.82H(2)O, were calculated) and scanning electron microscopy. The influence of the applied voltage and deposition time on the electrophoretic deposition of boehmite coatings on titanium from aqueous sol was investigated. The deposition was performed at constant voltage between 1.0 and 10 V and for a constant deposition time between 10 and 30 min. An increase in the applied voltage and deposition time increased the mass of the boehmite deposit, its welt as the amount of evolved hydrogen, causing a more porous structure. It was shown that boehmite coatings of maximum thickness, low porosity and good adhesion can be formed at lower deposition voltage and longer deposition time.
