ZIRCONIA POWDER FOR LASER SINTERING, AND METHOD FOR PRODUCING ZIRCONIA SINTERED BODY BY LASER SINTERING
To provide at least any one of novel zirconia powder for laser sintering by which sintering of zirconia by laser sintering is made possible without a need of interposing alumina and a compound other than zirconium compound, particularly, novel zirconia powder for laser sintering by which a dense sintered body of zirconia is obtained by irradiating laser, and a method for producing a sintered body by laser sintering by using the powder.SOLUTION: Zirconia powder for laser sintering contains oxygen-deficient zirconia and zirconia different from the oxygen-deficient zirconia, and furthermore, lightness value L* in L*a*b* color system is 94 or less.SELECTED DRAWING: Figure 1
【課題】アルミナの介在及びジルコニウム化合物以外の化合物を必須とせずに、レーザー焼結によるジルコニアの焼結を可能とする新規なレーザー焼結用ジルコニア粉末、特にレーザーを照射することで、緻密なジルコニアの焼結体が得られる新規なレーザー焼結用ジルコニア粉末、及び、これを用いたレーザー焼結による焼結体の製造方法の少なくともいずれかを提供する。【解決手段】酸素欠損ジルコニア、並びに、前記酸素欠損ジルコニアとは異なるジルコニアを含み、なおかつ、Ｌ＊ａ＊ｂ＊表色系における明度Ｌ＊が９４以下である、レーザー焼結用ジルコニア粉末。【選択図】図１
