The ceramic Material, Which has a unique Zn - Bi - Si - Ti formula system, and rare earth material Er2O3 as additives can be sintered at 950℃ for the following. Muhilayer chip varistor of pure silver as inner electrode was obtained by using the silver paste of 850℃ as internal electrode and the conventional chip varistor process. Obtained products have following advantages:varistor voltage (39V), nonlinear coefficent ( 〉 30) ,leakage current( 〈 21xA). the devices of 0805 size have a peak current( 8/20μS, 〉 100A), and a energy tolerance(10/1000μS, 〉0.3J).
