Effect of Thermal Decomposition Accompanying With Oxidation on TiO2 Capacitor-varistor Ceramics

Abstract

Abstract: The influence of oxide such as CuO and MnO₂ which have the character of decomposition accompanying with oxidation on the TiO₂ capacitor-varistor ceramics was studied. Based onthe results of C - V analysis, I - V analysis and dielectric measurements, their working mechanismwas analyzed. The results show that the decomposition accompanying with oxidation is useful forincreasing the surface state density and the height of grain-boundary barrier, and therefore improves the nonlinear property of TiO₂ capacitor-varistor ceramics.

Key words: TiO₂ capacitor-varistor ceramics, CuO, MnO₂, grain-boundary barrier
