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 prepared by direct mixing of constituent phases
(Japan Inst Metals & Materials, Sendai, 2000)
ZnO varistors with non-linearity coefficients reaching 50 and low values of the leakage current (similar to0.01 A/m(2)), were obtained by a method referred to as "direct mixing of constituent phases". The method is based ...
