摘要

In 1968, Dr. Matsuoka and his colleagues at Zmatsushita Electric Company disccovered the devices which are now called metal oxide varistors. These materials, consisting of ZnO mixed with small quantities of bismuth and other metal oxides, can have extremely non-linear voltage-current behavior. Unfortunately, the performance of these devices is often limited by the mechanical powder mixing technology (e.g.ball-milling) typically used in production. Raychem has developed and scaled-up a chemistry-based manufacuring process for ZnO varistor powder. This new proess, which eliminates all of the disadvantages of the conventional mixing processes, iks described in comparison with the traditional methods. Some electrical performance characteristics of the surge arrester disks made from this powder are also presented.
