Zirconia ceramic and preparation method thereof
The invention provides zirconia ceramic and a preparation method thereof, and belongs to the technical field of ceramic. The preparation method comprises the following steps: firstly, mixing zirconium oxide, yttrium oxide, niobium pentoxide, erbium oxide, a dispersing agent and water to obtain mixed slurry; sequentially carrying out sanding, spray granulation and dry pressing molding on the mixed slurry to obtain a ceramic body; finally, the ceramic green body is subjected to glue discharging and sintering in sequence, and the zirconia ceramic is obtained. The zirconia ceramic prepared by the invention has a photochromic effect, reversible color change can be generated by alternately performing 365nm ultraviolet irradiation and heating treatment, and the developing-decolorizing process has high reversibility and long cycle life.
本发明提供了一种氧化锆陶瓷及其制备方法,属于陶瓷技术领域。本发明首先将氧化锆、三氧化二钇、五氧化二铌、氧化铒、分散剂和水混合,得到混合浆料;再将混合浆料顺次进行砂磨、喷雾造粒、干压成型,得到陶瓷坯体;最后将陶瓷坯体顺次进行排胶、烧结,得到氧化锆陶瓷。本发明制得的氧化锆陶瓷具有光致变色效应,通过交替进行365nm紫外光辐照和加热处理,可以发生可逆的颜色变化,且该显色‑脱色过程具有高的可逆性和循环寿命。
