| Abstract: | By doping spinel (Zn7Sb2O(12), A new series of varistors are developed. With a potential slop of about 100V/mm, a presure-sensitive voltage range of 82￣ 150V, a current carring capacity of 1600A/cm2 and a leakage of<2μA, they can satisfy the electronic technic requirements of China telephone exchange industry for the varistors of 82V, 100V, 120V and 150V. How spinel modifies zinc oxide crystles is technologically explained, and the microstructure of spinel and the effect of particle size on electronic performance of ceramic substrates are analyzed |
