摘　　要：本文用一种新工艺方法——溶液法制作 ZnO 阀片,使 ZnO 阀片的非线性系数和浪涌吸收能力都得到提高。新方法的要点是将添加剂以溶液形式加入 ZnO 粉料,使得添加剂在 ZnO 阀片中均匀分布。本文对 ZnO 阀片性能改善的原因进行了分析,认为主要是改善了阀片的微观均匀性和增加了阀片内完好晶界结的数目。A new method——solution method,is used to prepare ZnO varistors in this paper,by which the nonlinerindex and the surge-absorbing ability of ZnO varitors have been greatly improved.The key of the new me thod is to add the additives solu bilized to ZnO powders,so that the additives can be uniformly dispersed in ZnO vair stors.It is suggested in this paper,that the improvment in the properties of varistors is due to the improvment in micro uniformity and the increment in perfect grain-boundary junctions.
