Analysis of isothermal sintering of zinc-titanate doped with MgO
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
Influence of Bi2O3 on microstructure and electrical properties of ZnO-SnO2 ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The effects of small amounts (0.5; 1.0 and 1.5 mol. %) of bismuth oxide on the microstructure and electrical properties of ZnO-SnO2 ceramics have been studied. Starting powders of ZnO and SnO2 were mixed in the molar ratio ...
Investigation of zinc stannate synthesis using photoacoustic spectroscopy
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered ...
Far infrared properties of sintered PbTe doped with boron
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
Far infrared spectra of sintered PbTe doped with boron were analyzed. The measured infrared spectra were fated using a modified plasmon-phonnon interaction model with two additional oscillators (at about 195 cm(-1) and 285 ...
Cerium Oxide Based Nanometric Powders: Synthesis and Characterization
(Science of Sintering, 2007)
Nanometric powders of solid solutions of cerium oxide were obtained by a modified
glycine nitrate procedure. Solid solutions of the host compound CeO2 with one or more
dopants in the lattice were synthesized. Rare earth ...
