<p>PURPOSE:To stabilize quality and to improve varistor characteristics by dissolving metallic salt of additive composition containing Mn which is dissolved by polyatomic alcohole into alcohole and by sintering material powders which is added into zinc oxide alcohole slurry and hydrolyzed. CONSTITUTION:Among metallic salt of additive component, at least metallic salt of Mn is dissolved by polyatomic alcohol, and metallic salt or metallic salt solution of additive component containing this solution is dissolved by alcohole solution and then added into zinc oxide alcohol slurry. It is then hydrolyzed to acquire sediment which is homogeneously diffused and attached on a surface of ZnO powders at an order of atomic level. Fine structure where oxide of a number of additive components is interposed as a homogeneous intergranular phase among ZnO powders can be acquired by eliminating solvent from the sediment to prepare material powders and by burning them. Quality can be stabilized in this way, and varistor characteristics can be improved.</p> |
