摘要

A new method for the processing of time-dependent isothermal depolarization current in oxide varistors is proposed. It involves (i) a new model for kinetics of the depolarization current, which is related to the parameters of the localized states, (ii) an account of the distribution of the relaxation time (which takes place due to the structure inhomogeneity of ceramics) using the Kohlrausch-Williams-Watts stretched exponential function and (iii) the determination of the most probable relaxation time. The proposed method was tested using ZnO high-voltage varistors. The ionization energy (0.06 and 0.16eV) and the electron capture cross-section (10 ~(17) and 10 ~(16)cm ~2) of the bulk donor states in two ZnO varistor ceramics were estimated.
