Abstract
Varistors working in the 3-15 V battery voltage range can be obtained from ZnO ceramics formulated with Ba2SiO4 as the extra additive. The p resence of a large surface state density and a changing pattern of tra p states at the grain boundary interfaces are more significant than la rge grain size in attaining lower breakdown voltages, yet preserving h igher nonlinear coefficients (alpha) up to 25.
