<p>PURPOSE:To obtain a voltage non-linear resistor having a large non-linear coefficient by a method wherein glass frit, which is formed by adding a specific quantity of silver oxide and manganese oxide to a composition consisting of bismuth oxide, silicon oxide and boric anhydride, is added to silver paste for formation of an electrode part. CONSTITUTION:The title electrode material for voltage non-linear resistor contains glass frit, which is formed by adding silver oxide of 1 to 10 pts.wt. and manganese oxide of 1 to 10 pts.wt. to the composition of 100 pts.wt. consisting of bismuth oxide of 70 to 90wt.%, silicon oxide of 3 to 15wt.% and boric anhydride of 3 to 15wt.%, is added to silver paste for formation of an electrode part. As a result, a voltage non-linear resistor, having both varistor characteristics and capacitor characteristics and also having a large non-linear coefficient even after a surge current has been applied, can be obtained.</p> |
