Description

一种黑色铈稳定锆珠
技术领域
本发明属于陶瓷材料技术领域,尤其涉及一种黑色铈稳定锆珠。
背景技术
陶瓷、水泥等行业中,习惯使用球磨机进行磨粉,在以前大都使用钢球或钢锻作为研磨体,由于钢球或钢锻的重量大,现在一般使用陶瓷研磨体代替钢球或钢锻进行研磨。氧化锆陶瓷作为一种新型的陶瓷结构材料,具有优良的力学性能,并且质地轻、硬度高,已成为陶瓷开发的重点。然而,氧化锆陶瓷研磨体的耐磨性差,需要经常更换才能保证正常的生产,且抗冲击性能差,特别容易破碎,同时磨损后的研磨体不能再次利用,形成了严重的浪费。
发明内容
为了解决现有的氧化锆陶瓷研磨体耐磨性差、抗冲击性能差等问题,本发明提出一种黑色铈稳定锆珠,有效解决了氧化锆珠高强韧和高耐磨性的问题。
本发明的目的将通过以下技术方法实现:一种黑色铈稳定锆珠,组分包括氧化锆、二氧化铈、多晶WC、氧化铝、氮化硅和氧化钇,以质量分数计,氧化锆为60~70%,二氧化铈为10~16%、多晶WC为2~4%,氧化铝为5~10%、,氮化硅为2~4%和氧化钇6~8%。
优选的,所述的一种黑色铈稳定锆珠,向所述组分先采用研钵碾细,再加入有机溶剂和粘结剂,待混合均匀后,浆料经过造粒形成颗粒,颗粒放入到干燥箱中真空干燥,再将干燥后的颗粒烧结即可得到所述的黑色铈稳定锆珠。
优选的,所述的一种黑色铈稳定锆珠,所述有机溶剂为乙醇溶液,乙醇溶液的体积分数为30~60%。
优选的,所述的一种黑色铈稳定锆珠,每克所述组分中加入1~2ml的有机溶剂。
优选的,所述的一种黑色铈稳定锆珠,所述粘结剂为聚乙二醇或者聚乙烯醇。
优选的,所述的一种黑色铈稳定锆珠,每克所述组分中加入0.1~0.2ml的粘结剂。
优选的,所述的一种黑色铈稳定锆珠,所述干燥箱真空干燥的温度为50℃,颗粒放入到干燥箱中真空干燥8~12小时。
优选的,所述的一种黑色铈稳定锆珠,所述干燥后的颗粒放入管式炉中烧结,烧结时升温速率为5℃/min,管式炉升温至1600~1700℃,保温3~5小时,采用程序降温,降温速率为10℃/min。
与现有技术相比,本发明具有如下的有益效果:本发明通过加入多晶WC并掺杂合适比例的二氧化铈、氧化铝、氮化硅和氧化钇,提高了锆珠的冲击强度、硬度以及韧性,解决了氧化锆陶瓷的耐磨性和抗冲击性能的问题。
