本发明公开了一种硅酸锆陶瓷研磨介质及其制备方法，它涉及化工材料制备技术领域。所述的硅酸锆陶瓷研磨介质的配方包含85％‑90％澳洲锆英砂、1％‑3％的氧化钇、1％‑3％的碳酸钙、2％‑5％的高岭土、1％‑3％的石英粉、0.5％‑1.5％钠长石。用价格低廉的CaCO3、高岭土和石英部分替换氧化钇和氧化铝，虽然价格低廉，但是CaCO3高温分解出的CaO也可以同氧化钇协同起到稳定氧化锆的作用，而高岭土作为一种黏土具有很强的可塑性，对硅酸锆研磨珠成型的时候有很大的帮助；由于在成分里含有氧化钇和氧化钙双稳定剂，对氧化锆的稳定效果更好，做出的强度更高；烧结后的结构更紧密，降低烧结温度，从而降低成本。
Description
技术领域：
本发明涉及一种硅酸锆陶瓷研磨介质及其制备方法，属于化工材料制备技术领域。
背景技术：
锆英砂的烧结较困难，高温下靠固相扩散作用，其速度非常缓慢，难于烧结，常需加入某些氧化物促进其烧结。锆英砂在高温下熔融分解，其分解出的ZrO2如不进行稳定，随着温度的变化呈现出不同的晶体结构，并伴有较大的体积效应，造成产品开裂，这些条件都增加了硅酸锆珠的生产成本，并制约了产品的性能。在涂料、油墨等化工行业对硅酸锆研磨介质的需求越来越大，对品质的要求也越来越高。但是市场上的硅酸锆研磨珠却显现的比较混乱，有的价格高，性价比低，有些性能达不到生产使用要求，现有的硅酸锆珠密度都在3.8-4.0g/cm3,密度较低，磨耗偏大，抗压强度低。
发明内容：
针对上述问题，本发明要解决的技术问题是提供一种硅酸锆陶瓷研磨介质及其制备方法。
本发明的硅酸锆陶瓷研磨介质及其制备方法，所述的硅酸锆陶瓷研磨介质的配方包含85％-90％澳洲锆英砂、1％-3％的氧化钇、1％-3％的碳酸钙、2％-5％的高岭土、1％-3％的石英粉、0.5％-1.5％钠长石。
作为优选，所述的硅酸锆陶瓷研磨介质的配方进一步优选为：89％的澳洲锆英砂、1.5％的氧化钇、1.5％的碳酸钙、3％的高岭土、2％的石英粉、1％的钠长石。
所述的硅酸锆陶瓷研磨介质的制备方法为：将配方中的澳洲锆英砂中添加氧化钇，添加进碳酸钙，添加进高岭土、添加进石英粉、添加进钠长石制备出三批硅酸锆陶瓷研磨珠，此硅酸锆陶瓷研磨珠的烧结温度是1300℃，平均密度是4.18g/cm3，平均强度是450Mpa，平均磨耗率是0.08％/h。
本发明的有益效果：1、用价格低廉的CaCO3、高岭土和石英部分替换氧化钇和氧化铝，虽然价格低廉，但是CaCO3高温分解出的CaO也可以同氧化钇协同起到稳定氧化锆的作用，而高岭土作为一种黏土具有很强的可塑性，对硅酸锆研磨珠成型的时候有很大的帮助；
2.由于在成分里含有氧化钇和氧化钙双稳定剂，对氧化锆的稳定效果更好，做出的强度更高；
3.由于在成分中添加有高岭土，在成型中粉体之间粘合更好，烧结后的结构更紧密，提高强度、密度和降低磨耗率；
4.在成分中添加一定比例的钠长石充当烧结助剂，降低烧结温度，从而降低成本。
具体实施方式：
本具体实施方式采用以下技术方案：所述的硅酸锆陶瓷研磨介质的配方包含85％-90％澳洲锆英砂、1％-3％的氧化钇、1％-3％的碳酸钙、2％-5％的高岭土、1％-3％的石英粉、0.5％-1.5％钠长石。
作为优选，所述的硅酸锆陶瓷研磨介质的配方进一步优选为：89％的澳洲锆英砂、1.5％的氧化钇、1.5％的碳酸钙、3％的高岭土、2％的石英粉、1％的钠长石。
所述的硅酸锆陶瓷研磨介质的制备方法为：将配方中的澳洲锆英砂中添加氧化钇，添加进碳酸钙，添加进高岭土、添加进石英粉、添加进钠长石制备出三批硅酸锆陶瓷研磨珠，此硅酸锆陶瓷研磨珠的烧结温度是1300℃，平均密度是4.18g/cm3，平均强度是450Mpa，平均磨耗率是0.08％/h。
