Structural and electrical properties of ZnO varistors containing different spinel phases
(Elsevier Sci Ltd, Oxford, 2001)
Structural and electrical properties of ZnO varistors were investigated as a function of spinel composition. Six varistor mixtures differing only in chemical composition of spinel, were prepared by mixing separately ...
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 ...
Electrical and transport properties of nickel manganite obtained by Hall effect measurements
(Springer, Dordrecht, 2009)
Intrinsic resistivity and carrier transport parameters of sintered nickel manganite samples (NTC thermistor grade) were determined using a Hall effect measurement system based on the van der Pauw method. Powder mixtures ...
