    摘要： Disclosed is a voltage non-linear resistor comprising a sintered body composed mainly of zinc oxide, said sintered body including confronting main faces and a face side face connecting the main faces to each other, which has the side face coated with a coating glass layer containing barium oxide. The coating glass layer comprises 40 to 85% by weight of lead oxide, 3 to 25% by weight of boron oxide. 1.5 to 25% by weight of silicon oxide and 0.2 to 15% by weight of barium oxide. The barium oxide acts as a catalyst and exerts a function of completely burning an organic binder at a temperature lower than about 400.degree. C. where the reaction between the organic binder and zinc oxide is not substantially advanced.

    摘要： A nonlinear resistor comprising a sintered body containing zinc oxide as a major component and at least bismuth oxide and boron oxide and electrodes formed thereon, said sintered body having a higher .gamma.-form bismuth oxide phase concentration in upper and/or lower surface layers of the sintered body than in the inner portion of the sintered body, has stabilized properties against long-time voltage application. When the sintered body is further modified by making the .gamma.-form bismuth oxide phase concentration in the periphery portions of the upper and/or lower surface layers lower than that in the inner portions of the upper and/or lower surface layers, the resulting nonlinear resistor shows a higher long-duration current impulse withstand capability.

    摘要： A sintered product composed chiefly of zinc oxide. A paste composed of a glass powder, an organic binder and tin oxide having a catalytic activity for promoting the combustion of organic binder, is coated on the side surfaces of the sintered product. The paste coated on the sintered product is baked to remove by burning the organic binder in the paste. Then, electrodes are attached to the main surfaces of the sintered product to complete a non-linear resistor.
