Application analysis of micro and nano composites in restoring of bone tissue of the jaw
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Application of synthetic polymer biomaterials is very often used in biomedicine and
dentistry. That’s why the need for creating the new polymer biomaterials is more and more
obvious. Hydroxy-apatite, as a natural constituent ...
Preparation and properties of BaTi1-xSnxO3 multilayered ceramics
(Journal of the European Ceramic Society, 2007)
BaTi1-xSnxO3 (BTS) powders, with x ranging from 0 to 0.15, were synthesized by solid-state reaction technique. The powders were pressed and sintered at 1370 degrees C. Obtained BTS ceramics were investigated by X-ray ...
Far infrared properties of sintered PbTe doped with boron
(Belgrade : International Institute for the Science of Sintering, 2007)
Far infrared spectra of sintered PbTe doped with boron were analyzed. The measured infrared spectra were fitted using a modified plasmon-phonnon interaction model with two additional oscillators (at about 195 cm-1 and 285 ...
Structural and magnetic characterization of LiMn1.825Cr0.175O4 spinel obtained by ultrasonic spray pyrolysis
(Materials Research Bulletin, 2007)
Quaternary spinel oxide LiMn1.825Cr0.175O4 Powder was synthesized by using an ultrasonic spray pyrolysis method, without additional annealing. The crystal structure of the as-prepared powder was revealed by X-ray powder ...
Reaction sintering of the 2ZnO-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2007)
Sintering kinetics of the mechanically activated ZnO-TiO2 system was studied. Mixtures of ZnO and TiO2 powders were mechanically activated using a high-energy ball mill for different time intervals from 0 to 300 minutes. ...
Far infrared reflection spectroscopy of Zn2SnO4 ceramics obtained by sintering mechanically activated ZnO-SnO2 powder mixtures
(Elsevier Sci Ltd, Oxford, 2007)
A mixture of starting ZnO and SnO2 powders (molar ratio 2: 1) were mechanically activated for 10, 40, 80 and 160 min in a planetary ball mill and then isothermally sintered at 1300 degrees C for 2 h in order to obtain ...
Far infrared properties of bulk sintered and thin film Zn2SnO4
(Lausanne : Elsevier Science, 2007)
Room temperature far infrared reflectivity spectra of single phase spinel zinc-stannate thin films, prepared by rf magnetron sputtering on a glass substrate, and bulk sintered samples were measured. The sintered samples ...
Phase evolution in Ce-doped yttrium-aluminum-based particles derived from aerosol
(Oxford : Elsevier Sci, 2007)
The common nitrates precursor solution leading to the Y3Al5O12:Ce3+ (YAG:Ce) composition with 2 at.% of cerium, is ultrasonically atomised and introduced into the tubular flow reactor at 320 degrees C. Having in mind that ...
Monitoring of transformations in bentonite after NaOH-TMA treatment
(Oxford : Elsevier Sci, 2007)
Semi-quantitative methods of X-ray diffraction and FTIR-spectroscopy, accompanied by electron microscopy, X-ray microanalysis and others were used to monitor structural-phase reorganizations occurring in a smectite-gypsum ...
Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Oxford : Elsevier Sci Ltd, 2007)
Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since ...
