PURPOSE:To obtain a voltage-nonlinear resistance ceramic composition for low-voltage use having excellent resistance to surge current by using zinc oxide as a main component, adding specific amounts of oxides of Bi, Co, Mn, Ti, etc., as subsidiary components and adding oxides of Mo, W, etc., to the obtained composition. CONSTITUTION:The objective voltage-nonlinear resistance ceramic composition for low-voltage use is produced by including 0.01-2.00mol% of at least one kind of Mo and W in terms of MoO3 and WO3 in a composition composed mainly of ZnO and containing at least Bi, Co, Mn and Ti as subsidiary components in amounts of 0.05-3.00mol% each of Bi2O3, Co2O3 and MnO2 and 0.10-2.00mo1% of TiO2 in terms of Bi2O3, Co2O3, MnO2 and TiO2, respectively. |
