摘要： Nonohmic ZnO ceramics including the following additives have the voltage nonlinear exponent .alpha. of 30 or more, the dielectric constant .epsilon. of about 1000 or less, the loss factor (tan .delta.) of less than 10%, and small variations caused in the breakdown voltage V.sub.i by load and large current pulses. The additives listed by molecular formulae are given in % by mol. The glass components are given for Nos. 1 through 4 in % by weight, symbols of elements being representative of borosilicate lead and/or zinc glass.______________________________________ No. Bi.sub.2 O.sub.3 CoO MnO Sb.sub.2 O.sub.3 Glass Component ______________________________________ 1. 0.1-10 0.05-10 0.25-4 0.05-6 0.1-10 (Pb-Zn) 2. 0.1-6 0.05-10 0.25-10 0.1-10 0.1-10 (Zn) 3. 0.1-6 0.05-10 0.23-4 0.05-6 0.1-3 (Pb) 4. 0.1-6 0.05-10 0.2-10 0.1-6 0.1-10 (Zn and others) ______________________________________ As a fifth embodiment, the oxides corresponding or equivalent to a lead-borosilicate glass (PbO, B.sub.2 O.sub.3 and SiO.sub.2) may be included in certain amounts with varying amounts of zinc oxide as a major component along with Bi.sub.2 O.sub.3, CoO, MnO and Sb.sub.2 O.sub.3.
