Preparation method of blue zirconia ceramic
The invention discloses a preparation method of blue zirconia ceramic. The method comprises the following steps: S1, raw material mixing, S2, raw material ball milling, S3, dispersion and granulation, S4, static pressing and sintering and the like to prepare the blue zirconia ceramic. According to the preparation method of the blue zirconia ceramic, the nanoscale cobalt oxide is used as a coloring agent, and the nanoscale silicon dioxide is used as a sintering aid, so that the problems of uneven coloring and poor stability caused by high-temperature volatilization loss of the nanoscale cobalt oxide are solved, and the glossiness of the prepared blue zirconia ceramic is improved; and the surface tension of the particles is eliminated, so that the agglomeration phenomenon among the particles is avoided, the sintering temperature is reduced, the heat preservation time is short, the energy consumption is obviously reduced, the volatilization of the coloring agent is reduced, and the mechanical property of the ceramic is obviously improved.
本发明公开了一种蓝色氧化锆陶瓷的制备方法，通过S1原料混合、S2原料球磨、S3分散与造粒、S4静压与烧结等步骤，从而制得所述蓝色氧化锆陶瓷。本发明一种蓝色氧化锆陶瓷的制备方法，采用纳米级氧化钴作为着色剂，再通过纳米级二氧化硅作为烧结助剂，解决纳米级氧化钴因高温挥发损失导致的着色不均匀和稳定性差的问题，提高所制备的蓝色氧化锆陶瓷的光泽度，并消除颗粒的表面张力，以避免造成颗粒之间的团聚现象，同时降低了烧结温度，保温时间较短，显著降低能耗，并减少着色剂的挥发，显著提高陶瓷的力学性能。
