高纯部分稳定二氧化锆微粉的制备工艺

The Manufactural Technology of the Partially Stabilized Zirconia

高纯 Zr O2微粉作为高温高强特种陶瓷和耐火材料等的重要原料 ,由于晶型转变所引起的体积效应而影响其耐高温性能 ,限制其应用范围 ,因此必须进行晶型稳定化处理 .

ZrO2, used as the important raw materials of the special ceramics of high temperature and high strength and refractory, owing to the transform of crystal type causes volume effect, thus influencing its heatresistance and limits its application, must be put to the disposition of stabilization of crystal type This article emphatically recommends the manufactural technology and qualitative standard of the partially stabilized zirconia which uses yttria as stabilizer
