Zirconium oxide composition, zirconium oxide sintered body and preparation method
The invention provides a zirconium oxide composition, a zirconium oxide sintered body and a preparation method. The zirconium oxide composition comprises zirconium oxide, a stabilizer and a fluorescent agent, the fluorescent agent comprises thulium oxide and erbium oxide; wherein on the basis of the mass of the zirconium oxide composition, the content of the thulium oxide is 6-20wt%; according to the monatomic mass, the ratio of Tm to Er is (8-20): 1; the zirconia sintered body is prepared from the zirconia composition through dry pressing molding, isostatic pressing treatment and sintering in sequence. According to the zirconia composition, specific fluorescent agent components are selected, and the content and the proportion of the fluorescent agent components are controlled, so that on one hand, the problems that a prosthesis is greatly different from natural teeth and cannot be coordinated with adjacent teeth when exposed to ultraviolet light are solved from the bionic aesthetic effect; and on the other hand, the problems of complicated operation steps and high cost due to the fact that various powders need to be blended respectively when the fluorescent zirconium oxide restoration is prepared at present are solved.
本发明提供了一种氧化锆组合物、氧化锆烧结体及制备方法，所述氧化锆组合物包括氧化锆、稳定剂以及荧光剂；所述荧光剂包括氧化铥和氧化铒；其中，以氧化锆组合物的质量为基准计，所述氧化铥的含量为6‑20wt％；以单原子质量计，Tm:Er＝(8‑20):1；所述氧化锆烧结体采用上述氧化锆组合物依次通过干压成型、等静压处理以及烧结制备得到；所述氧化锆组合物通过选择特定的荧光剂组分，并控制其含量以及配比，一方面，从仿生美学效果上解决了修复体暴露在紫外光下将与天然牙的差别较大，不能与邻牙协调的问题；另一方面解决了目前制备荧光氧化锆修复体时需要分别调配多种粉体，操作步骤繁杂、成本高的问题。
