A seris of phys ics index test was taken such as the water absorption ,volume density ,wear proof ,microhardness ,cross breaking strength and fracture tough ness ect. Also low - temperature sintering machanism and the method of raising wearability was described in this article. Analyse the influ ence of technology on product physics index combining the microstructure. Key words :High - alumina clay ;85 alumina ceramics ;Low - temperature firing ;Wear - resisting ;Detrition microstructure 85 瓷并获得成功。同时结合电镜照片分析了生产工 　前言 艺对产品质量的影响。经测试该产品性能指标达到甚 至超过国内同类产品的标准 ,提高了资源利用率 ,降低
