    摘要： A rare-earth oxide sintered body, or corrosion-resistant material, having low sintering temperature and high density is prepared by adding a boron compound at a ratio of 0.06 mol % or more and less than 25 mol % when converted into boron oxide (B2O3) to oxide powder of at least one of La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, and Sc, after which the mixed powder is formed and sintered. The sintered body comprises at least one of La2O3, Nd2O3, Sm2O3, Eu2O3, Gd2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3, Lu2O3, and Sc2O3, and at least one of Ln3BO6 (Ln=La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, and Lu), and Sc3BO6 as a main constituent crystal thereof.

    摘要： A ceramic member having a high density, small grain diameter, and excellent plasma resistance is provided. The ceramic member is constituted of a fine structure composed of fine grains, which is a ceramic member comprising an yttria as a main component and obtained through firing, wherein the ceramic member has an open porosity, as determined through a measurement by the Archimedes method, of less than 0.5%. By diminishing open voids, sites which is an origin of plasma erosion can be diminished. Thus, a ceramic member having excellent plasma resistance can be provided. By inhibiting abnormal grain growth to form a ceramic member constituted of stall grains, particle contamination by dusting can be reduced. Thus, plasma resistance and preventing particulate contamination can be improved.
