Cuttable zirconia porcelain block for dentistry and preparation method of cuttable zirconia porcelain block
The invention discloses a machinable zirconium oxide porcelain block for dentistry and a preparation method thereof, and belongs to the technical field of preparation of dental repair materials.The preparation method comprises the steps that stable zirconium oxide powder is subjected to powder laying forming in a grinding tool, and a zirconium oxide initial blank is obtained; embedding the zirconium oxide initial blank into a certain amount of exothermic system reactant to obtain an embedded material; placing the embedding material in a high gravity field, and initiating an exothermic reaction system to sinter the zirconium oxide initial blank; after sintering in a high gravity field, cooling and taking out to obtain a zirconium oxide ceramic block blank; and carrying out appearance processing on the zirconium oxide porcelain block green body to obtain the machinable zirconium oxide porcelain block for the dentistry. The preparation method is simple, high in efficiency and suitable for large-scale production, and the obtained zirconia ceramic block is low in porosity and high in density.
本发明公开了一种齿科用可切削氧化锆瓷块及其制备方法，属于齿科修复材料制备技术领域，通过将稳定氧化锆粉体在磨具中进行铺粉成型，获得氧化锆初坯；将所述氧化锆初坯包埋入一定量的放热体系反应物中，获得包埋物料；将所述包埋物料置于超重力场中，引发放热反应体系对氧化锆初坯进行烧结；在超重力场中烧结完成后，冷却取出，获得氧化锆瓷块坯体；对所述氧化锆瓷块坯体进行外形加工，获得所述的齿科用可切削的氧化锆瓷块。制备方法简单、效率高，适合大规模生产，所获得的氧化锆瓷块孔隙率低、致密度高。
