how to produce varistor

1. In a method for producing a voltage dependent resistor consisting mainly of a sintered body of zinc oxide and about 0.1-10% by weight of bismuth oxide in which , there is optionally present, small quantities of oxides of other metals and which body is provided, at opposite faces thereof, with ohmic electrodes, wherein the improvement comprises sintering a mixture of zinc oxide and oxides of metals which may be optionally present, at a temperature of between about 900 degree.C-1450.degree .C, in an atmosphere containing bismuth oxide to produce a sintered body and then applying the ohmic electrodes to the resultant sintered body.
The apply range of the ZnO varistor is more and more comprehensive, with advanced facilities and strict controlling, Hongzhi Enterprises Co. can fill in you in this domain.
