Zirconium oxide composition, zirconium oxide presintered body and preparation method thereof, zirconium oxide sintered body and preparation method thereof, and zirconium oxide dental product
The invention provides a zirconium oxide composition, a zirconium oxide presintered body and a preparation method thereof, a zirconium oxide sintered body and a preparation method thereof, and a zirconium oxide dental product, and relates to the technical field of dental ceramic materials, the zirconium oxide composition comprises zirconium oxide and a coloring agent, the coloring agent comprises a coloring agent and a fluorescent agent, the coloring agent comprises a first coloring agent, a second coloring agent and an optional third coloring agent, and the fluorescent agent comprises at least one of a first fluorescent agent, a second fluorescent agent and a third fluorescent agent; according to the zirconium oxide composition provided by the invention, the coloring agent and the fluorescent agent are matched with each other, and are mixed with zirconium oxide for sintering, so that the zirconium oxide sintered body and the zirconium oxide dental product which have inherent fluorescence and are close to natural teeth in color and fluorescence can be prepared; and meanwhile, the prepared zirconium oxide sintered body and the zirconium oxide dental product are improved in light transmittance and fracture toughness, stable in color and low in cost, and batch production is easy to realize.
本发明提供了一种氧化锆组合物、氧化锆预烧体及制备方法、氧化锆烧结体及制备方法和氧化锆牙科制品，涉及牙科陶瓷材料技术领域，所述氧化锆组合物包括氧化锆和染色剂，染色剂包括着色剂和荧光剂，所述着色剂包括第一着色剂、第二着色剂和任选的第三着色剂，所述荧光剂包括第一荧光剂、第二荧光剂和第三荧光剂中的至少一种；本发明提供的氧化锆组合物通过着色剂与荧光剂相互搭配，与氧化锆混合后烧结，能够制备得到本身固有荧光，且颜色及荧光接近于自然牙的氧化锆烧结体及氧化锆牙科制品，同时制备得到的氧化锆烧结体及氧化锆牙科制品透光性及断裂韧性提高，颜色稳定，成本低，容易实现批量生产。
