摘要：

Microstructural features and elemental distribution characteristics of the spinel phase in ZnO varistors have been investigated by electron probe microanalysis and transmission electron microscopy. The distribution characteristics of minor additive elements including Co, Mn, Ni and Cr in different phases are also examined. The V-I characteristics of two types of sample, possessing identical intergranular phase, are compared and discussed in relation to the spinel characteristics. © 1990 Chapman and Hall Ltd.
