ABSTRACT:
A zinc oxide voltage-nonlinear resistor is described. The resistor is produced by sintering a zinc oxide mixture containing 0.08 to 5.0 atomic % of at least one rare earth element, 0.1 to 10.0 atomic % of cobalt, 0.01 to 1.0 atomic % of at least one member of potassium, cesium, and rubidium, 0.01 to 1.0 atomic % of chromium, and 5.times.10.sup.-4 to 1.times.10.sup.-1 atomic % of boron, the balance being zinc oxide. This resistor has superior voltage nonlinearity and is greatly improved in the short duration discharge current withstand capability and the life performance under application of electricity.
