摘要: A voltage non-linear resistance ceramics having a larger voltage non-linear coefficient and a superior protection ability against the overvoltage is prepared by firing an essential component of zinc oxide added with the accessary components of one or more elements in the form of elements or compounds. As the accessary components, at least one of magnesium and calcium in addition to praseodymium, cobalt, potassium and chromium in the predetermined amounts are added to obtain a voltage non-linear resistance ceramics with a sufficient reduction of the leakage current and an increased protection ability against the overvoltage.

摘要: A method of producing a voltage nonlinear ZnO varistor in which seed grains of ZnO are produced by spray drying a slurry of ZnO particles and then sintering the dried slurry to form seed grains having a size of 10 to 100.mu.m. The seed grains are mixed with a ZnO powder of particles of much smaller size than the seed grains and a small amount of an auxiliary component. The mixture is then molded and sintered to form the varistor element to which electrodes are attached.
