【Abstract】 The non-linear, electric, aging and chemical performance of ZnO varistorwere closely related with its structure, composition, properties and the boundarybetween phases at grain boundary. The conduct of grain boundary and the influencefactors of process to grain boundary were discussed. The mechanism of grain boundaryabout ZnO varistor conductivity and aging were analyzed. Many studies showed thatmost of properties of ZnO varistor were the phenomena of grain boundary.更多还原
