Description

一种耐磨氧化锆陶瓷的制作方法
技术领域
本发明涉及一种耐磨氧化锆陶瓷的制作方法。
背景技术
纯净的氧化锆是白色固体，含有杂质时会显现灰色或淡黄色，添加显色剂还可显示各种其它颜色。纯氧化锆的分子量为123.22，理论密度是5.89g/cm3，熔点为2715℃。通常含有少量的氧化铪，难以分离，但是对氧化锆的性能没有明显的影响。氧化锆有三种晶体形态：单斜、四方、立方晶相。常温下氧化锆只以单斜相出现，加热到1100℃左右转变为四方相，加热到更高温度会转化为立方相。由于在单斜相向四方相转变的时候会产生较大的体积变化，冷却的时候又会向相反的方向发生较大的体积变化，容易造成产品的开裂，限制了纯氧化锆在高温领域的应用，其耐磨性能一般，如何提供一种耐磨氧化锆陶瓷的制作方法成为研究课题。
