By the main phase and second phase analysis of TiO<sub>2</sub> varistor-ceramic through XRD and EDAX, the effects of the second phrase on TiO<sub>2</sub> varistor-ceramic were studied. Grain size and its distribution were observed through scanning electron microscope and the density of porcelain body was measured. The effects of grain size, distribution and density of ceramic body on electrical property of TiO<sub>2</sub> varistor-ceramic were the focus issue for analysis. The increased molding density would improve the densifying of magnetic body to some extent and promote grain growth.展开更多
