Study of non-ohmic electrical behavior and microstructure of ZnO-V2O5 varistor

Electronic ceramics based on ZnO with 1,2,3,4 and 5 mol% of V2O5 were prepared by conventional powder processing route and sintered at 1000 C for 2 hour. Microstructure of samples was investigated by X-Ray and SEM. It was observed that the microstructure of the samples consists of ZnO grains as main phase, and the density of samples was increased with increase in V2O5 content. All of the prepared ceramics showed characteristic of non-ohmic current – voltage behavior. Non-linear coefficient increased with increase in V2O5 content. The non-linear electrical behavior was explained by considering formation of the potential barriers at grain boundaries.
