LIGHT TRANSMISSIVE ZIRCONIA SINTERED BODY, MANUFACTURING METHOD THEREFOR, AND APPLICATION THEREFOR
PROBLEM TO BE SOLVED: To provide a zirconia sintered body having high light transmissivity and high strength.SOLUTION: There is provided a zirconia sintered body containing cubic crystal particles having a tetragonal domain, solid dissolving at least one kind of neodymium, praseodymium and gadolinium and a stabilizer, and having average crystalline diameter calculated from half width of a peak of 2θ=30±2° in a powder X ray diffraction pattern with CuKα as a radiation source of over 255 nm. There is provided a zirconia sintered body having content of at least one of neodymium, praseodymium and gadolinium of 0.1 to 10 mol%. There is provided a zirconia sintered body where the stabilizer is at least one kind from yttria, scandia, calcia, magnesia or ceria.SELECTED DRAWING: Figure 2
【課題】高い透光性及び高い強度を兼備したジルコニア焼結体の提供。【解決手段】正方晶ドメインを有する立方晶の結晶粒子を含み、ネオジム、プラセオジム及びガドリニウムからの少なくとも１種と、安定化剤とを固溶し、なおかつ、ＣｕＫαを線源とする粉末Ｘ線回折パターンにおける２θ＝３０±２°のピークの半値幅から算出される平均結晶子径が２５５ｎｍ超であるジルコニア焼結体。ネオジム、プラセオジム又はガドリニウムから少なくとも１種の含有量が０．１〜１０ｍｏｌ％であるジルコニア焼結体。安定化剤が、イットリア、スカンジア、カルシア、マグネシア又はセリアからの少なくとも１種であるジルコニア焼結体。【選択図】図２
