| Abstract | Y(NO3)3·6H2O-doped ZnO-Bi2O3-based varistor ceramics were prepared using a solid reaction route. The microstructure, electrical properties, degradation coefficient(DV), and dielectric characteristics of varistor ceramics were studied in this paper. With increasing amounts of Y(NO3)3·6H2O in the starting composition, Y-containing Bi-rich, Y2O3, and Sb2O4 phases were formed, and the average grain size decreased. Results also showed that with the addition of0.16 mol% Y(NO3)3·6H2O, Y(NO3)3·6H2O-doped ZnO-based varistor ceramics exhibit comparatively better comprehensive electrical properties, such as a threshold voltage of425 V/mm, a nonlinear coefficient of73.9, a leakage current of1.78μA, and a degradation coefficient of1.7. The dielectric characteristics and lightning surge test also received the same additional content of Y(NO3)3·6H2O. The results confirmed that doping with rare earth nitrates instead of rare earth oxides is very promising route in preparing high-performance ZnO-Bi2O3-based varistor ceramics.?2011 Elsevier B.V.
