摘要: The varistor element contains zinc-oxide as a main constituent and at least bismuth and antimony as accessory constituents. The content of bismuth in the form of Bi.sub.2 O.sub.3 is in a range from about 0.1 to 4.0 mol % and the content of antimony in the form of Sb.sub.2 O.sub.3 constitutes a mol-ratio of Sb.sub.2 O.sub.3 /Bi.sub.2 O.sub.3 less than or equal to about 1.0 mol %. These materials are mixed thoroughly and are pressed into a compact. After coating both sides of the compact with Ag or Ag--Pd paste, the compact and its electrodes are sintered simultaneously at a temperature of about 800.degree. C. to 960.degree. C.

摘要: A product and process of making such product in which a varistor is formed by diffusing lead borosilicate-type glass, into a surface of a fired or sintered zinc oxide substrate, i.e., "varistor element," during formation of an electrode on the surface of the substrate. Typically, an electrode paste or material, comprising a mixture or lead borosilicate-type glass frit and Ag powder, is applied to the substrate and provides the lead borosilicate-type glass for diffusing into the substrate. The improvement is that the lead borosilicate-type glass frit for the electrode paste or material comprises a mixture of PbO, B.sub.2 O.sub.3, SiO.sub.2 and at least one metal oxide selected from the group consisting of cobalt oxide, magnesium oxide, yttrium oxide, antimony oxide, manganese oxide, tellurium oxide, lanthanum oxide, cerium oxide, praseodium oxide, neodymium oxide, samarium oxide, europium oxide, gadolinium oxide, terbium oxide, dysprosium oxide, holmium oxide, erbium oxide, thulium oxide, ytterbium oxide and lutetium oxide.
