Zirconium oxide sintered body and method for producing same
Provided are: a zirconia sintered body having excellent bending strength, breaking toughness, and light transmittance depending on the content of yttrium oxide; and a method for producing the zirconia sintered body. The present invention relates to a zirconia sintered body which contains zirconia particles and satisfies A15/A50lt. 0.60 (A15 represents the particle diameter at which the cumulative area when the area of each zirconia particle is calculated in a SEM photograph of the zirconia sintered body and the particles having small areas are sequentially cumulated reaches 15% of the total area; and A50 represents the particle diameter when the cumulative area reaches 50% of the total area. The total area represents the total area of the areas of the zirconia particles in the SEM photograph. ).
本发明提供根据氧化钇的含有率而在弯曲强度、破坏韧性和透光性方面优异的氧化锆烧结体及其制造方法。本发明涉及氧化锆烧结体，其包含氧化锆颗粒，且满足A15/A50<0.60(A15表示在氧化锆烧结体的SEM照片中计算各氧化锆颗粒的面积，从面积小的颗粒起依次进行累计时的累计面积达到总面积的15％时的粒径；A50表示累计面积达到总面积的50％时的粒径。前述总面积表示SEM照片中的氧化锆颗粒的面积的总面积。)。
