PROBLEM TO BE SOLVED: To obtain a high-density sintered body.SOLUTION: Indium oxide powder is used, which is obtained by calcinating indium hydroxide powder in which each orientation index of (200) plane and (400) plane determined by Wilson formula is 2.0 or higher, the orientation index of (442) plane is 0.5 or lower, the ratio of the orientation index of (400) plane to the orientation index of (200) plane is 1.5 or higher, and each diffraction peak on (220) plane and (420) plane does not appear. |
