ZnO压敏电阻器生产工艺的改进

Improvement of the performance of ZnO varistors by improving the technology

压敏电阻器的生产工艺是影响产品质量的重要因素之一。通过试验，对生产工艺中，影响ＺｎＯ压敏电阻器直流老化性能的因素，如原材料细度、烧成气氛、成型密度、热处理温度和时间、掺杂等进行了研究，并据此确定了最佳工艺条件。

豹he factors that will affects the DC Aging Property such as particle size of raw material, sintering atmosphere, density of shaped disks, temperature and time of heat treatment and doping are studied Based on the result, the optimized technology is determined(4 refs)
