Microstructural and compositional aspects of ZnO-based varistor ceramics prepared by direct mixing of the constituent phases and high-energy milling
(Elsevier Sci Ltd, Oxford, 2008)
ZnO-based varistor samples were prepared by the direct mixing of the constituent phases (DMCP) and sintering at 1100 degrees C for 2 h. The influence of the starting powder mixture's composition - the amounts of the ...
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 ...
