LIGHT TRANSMISSIVE ZIRCONIA SINTERED BODY, MANUFACTURING METHOD THEREFOR AND APPLICATION THEREOF
PROBLEM TO BE SOLVED: To provide a light transmissive zirconia body having transmissivity equal to a titania-containing light transmissible zirconia sintered body, without need of a fluorine compound and capable of being produced more stably than conventional titania-containing light transmissible zirconia sintered body.SOLUTION: There is provided a zirconia sintered body consisting of zirconia where 2.5 mol% to 25 mol% of at least one of calcia or magnesia, and yttria and having average crystalline particle calculated from half width of a peak at 2θ=30±2° in an XRD measurement with a CuKα ray as a radiation source of 400 nm or less.SELECTED DRAWING: Figure 3
【課題】チタニア含有透光性ジルコニア焼結体に匹敵する透明性を有するジルコニア焼結体であって、フッ素化合物を必須とせず、なおかつ、従来のチタニア含有透光性ジルコニア焼結体よりも安定して生産することができる透光性ジルコニア焼結体を提供することを目的とする。【解決手段】２．５ｍｏｌ％以上２５ｍｏｌ％以下のカルシア又はマグネシアの少なくともいずれかとイットリアが固溶したジルコニアからなり、ＣｕＫα線を線源とするＸＲＤ測定において、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４００ｎｍ以下であることを特徴とするジルコニア焼結体。【選択図】図３
