ZIRCONIA POWDER, METHOD OF PRODUCING ZIRCONIA SINTERED BODY, AND ZIRCONIA SINTERED BODY
To provide zirconia powder that has excellent moldability, has a high sintered density, and can easily form a colored zirconia sintered body by a simple method.SOLUTION: The zirconia powder comprises zirconia containing yttria in an amount in a range of not lower than 2 mol% and not higher than 6 mol%, and one or more oxide selected from the group consisting of Group 4 to Group 9, Group 12 and Group 14, and lanthanoid. The volume of pores of the zirconia powder having a pore diameter of not larger than 200 nm is from 0.14 to 0.28 mL/g, and the relative molding density when molded at a molding pressure of 1 t/cm2 is from 44 to 55%.SELECTED DRAWING: None
【課題】 成型性に優れ、高い焼結密度を有し、簡便な方法でカラージルコニア焼結体を製造することができるジルコニア粉末を提供すること。【解決手段】 イットリアを２ｍｏｌ％以上６ｍｏｌ％以下の範囲内で含むジルコニアと、第４族～第９族、第１２族、第１４族及びランタノイド元素からなる群より選ばれる１種以上の酸化物とを含み、細孔径２００ｎｍ以下の細孔容積が０．１４～０．２８ｍＬ／ｇであり、成型圧１ｔ／ｃｍ２で成型した場合の相対成型密度が４４～５５％であるジルコニア粉末。【選択図】 なし
