摘要：
The effect of Dy2O3 incorporation on microstructure and electrical properties of ZnO-Pr6O11-CoO-Cr2O3- Dy2O3 (in short ZPCCD)-based varistors was investigated. Microstructure was examined by a scanning electron microscope (SEM). The average grain size (d) was determined by the lineal intercept method. The crystalline phases were identified by an X-ray diffractometry (XRD) with CuKα radiation. The density (ρ) of ZPCCD-based ceramics was measured by the Archimedes method.
