ZNO-Bi2O3-based varistor ceramics prepared by direct high-energy ball milling of the dopants

摘要：

The microstructure and electrical properties of ZnOBi2O3-based varistor ceramics prepared by direct high-energy ball milling of the dopants were studied. The varistor ceramics samples were characterized by XRD and SEM analysis, as well as by dc electrical measurements, such as the nonlinearity coefficients, leakage current and threshold voltage. The best electrical characteristics were found in sample P2, which exhibited the threshold voltage was 347 V/mm, nonlinear coefficient was 39.2 and leakage current was 0.18 uA.
