<p>CERMET VARISTORS The cermet varistors have electrodes applied to an improved varistor composition which includes a semiconductive material having zinc oxide in admixture with at least one metal oxide selected from the group consisting of chromium oxide, cobalt oxide and manganese oxide and includes a glass matrix. The glass matrix is a borosilicate glass with at least one metal oxide selected from the group consisting of cobalt oxide and manganese oxide. The improved compositions are used in varistors of both the thick film and bulk types, the resulting varistors having enhanced device characteristics, particularly high exponents of nonlinearity.</p> |
