技术领域
本发明属于研磨介质领域，更具体的说涉及一种高耐磨锆铝复合陶瓷球及其生产工艺。
背景技术
随着粉体超细技术的飞速发展，电子、造纸、陶瓷、化工、油漆、油墨、塑料等行业对粉体细度的要求越来越高，甚至有些粉体需达到纳米级。使用超细粉体后，材料的性能会得到提高。国内外采用物理方法对物料进行超细研磨，最佳、最经济的方法是湿法研磨，该工艺中必不可少地要用到各类直径规格的陶瓷研磨介质。
现有的锆铝复合陶瓷球所使用的配方，及相适配的工艺，为达到硬度大于1000HV，和磨耗较小的情况下均需使用大量的ZrO2，使整体成本较高。
发明内容
针对现有技术的不足，本发明提供了一种在保证复合陶瓷球密度和硬度的同时，降低生产成本的高耐磨锆铝复合陶瓷球。
为实现上述目的，本发明提供了如下技术方案：一种高耐磨锆铝复合陶瓷球，配方中各组分的质量份数如下：
95％≥Al2O3≥80％；
15％≥ZrO2≥3％；
7％≥Y2O3+SiO2+CeO2≥1％；
6％≥CaO+MgO≥1％。
进一步的其晶相成分为：
刚玉≥75％；
18％≥氧化锆≥3％；
12％≥镁铝尖晶石≥2.5％；
8％≥钙长石≥2.5％；
8％≥其它晶相。
一种高耐磨锆铝复合陶瓷球的生产工艺，包括如下步骤：
1)原料制备：将配方中所有原材料混合均匀，采用湿法球磨至中径小于1um，喷雾干燥得到超细粉体；
2)成型：将超细粉体置于成球机内，加水混合搅拌均匀，过筛制得粒径为0.1-0.5mm的种球，将种球加入成球机内，向种球上不断加入水和超细粉体，直至种球变大至0.2mm-15mm的陶瓷球生坯；
3)烧结：将陶瓷球生坯在窑炉内按照60℃/hr升温至300℃，然后保温1hr，再按照120℃/hr升温至1450℃，保温4小时，再自然冷却至室温。
与现有技术相比，本发明的有益效果是：本发明能够在保证最终陶瓷球耐磨性和硬度的前提下，降低生产成本，同时Y2O3与CeO2能够起到对ZrO2稳定的作用。
