<p>PURPOSE:To obtain a voltage-dependent nonlinear resistor whose characteristics are stable and not irregular by means of a granulation operation using a spray drier without temporarily baking silicon dioxide even when the amount of silicon dioxide added is large. CONSTITUTION:In the manufacturing method of a voltage-dependent nonlinear resistor, a zinc oxide raw material powder which contains zinc oxide as its main component and at least silicon dioxide as its additive is granulated, molded and baked. In the manufacturing method, a silicon dioxide powder is covered with a resistor-constituent-element simple substance or its oxide.</p> |
