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 ...
Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Elsevier Sci Ltd, Oxford, 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 ...
ZnO varistors with reduced amount of additives prepared by direct mixing of constituent phases
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to reduce number of additives using new method of preparation, refered as "direct mixing of the constituent phases". The method is based on sintering of a mixture of constituent phases with the ...
Structure and Properties of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(11th European Meeting on Ferroelectricity, Bled, Slovenia, 3-7 September 2007, 2007)
Recently there has been renewed interest in the properties
of the Aurivillius phases as temperature-stable ferropiezoelectrics
[1 ]. Several bismuth-layered crystal structures
and their properties have been investigated ...
ZnO varistors from intensively milled powders
(Elsevier Sci Ltd, Oxford, 2007)
Two ways of application of intensive milling in ZnO varistors processing were compared. First was intensive milling of mixture of previously prepared constituent phases. In this case, intensive milling was applied only to ...
