ABSTRACT:
A voltage nonlinear resistor of a sintered substance of a composite consisting essentially of zinc oxide and containing at least one rare earth element and at least one additional rare earth element selected from the group consisting of Eu, Gd, Tb, Dy, Ho, Y, Er, Tm, Yb, and Lu, and Bi and Sb. Spacing d.sub.n (.ANG.) provided from precipitation grains formed in zinc oxide grains or on a grain boundary lies in the range of 2.85 .ANG..ltoreq.d.sub.1 .ltoreq.2.91 .ANG., 1.83 .ANG..ltoreq.d.sub.2 .ltoreq.1.89 .ANG., 1.77 .ANG..ltoreq.d.sub.3 .ltoreq.1.82 .ANG., 1.56 .ANG..ltoreq.d.sub.4 .ltoreq.1.61 .ANG., 1.54 .ANG..ltoreq.d.sub.5 .ltoreq.1.60 .ANG.. The spacing mentioned here is a spacing obtained according to the Bragg condition in the X-ray diffraction method.
