PURPOSE:To provide a voltage nonlinear resistor of zinc oxide where the voltage nonlinear coefficient is great, and the leak current is small, and the change of the varistor voltage due to large current pulse application is small. CONSTITUTION:Using zinc oxide (ZnO) as a main ingredient, bismuth oxide (Bi2O3) cobalt oxide (CoO), manganese oxide (MnO), antimony oxide (Sb2O3), and borosilicate zinc glass frit are mixed as subingredients, and further zirconium oxide (ZrO2) is added and mixed by 0.05-5.9mol.% to form a sintered substance. |
