    摘要： A titanium sintered body is composed of a material containing titanium, and has an oxygen content of 2500 ppm by mass or more and 5500 ppm by mass or less and a surface Vickers hardness of 250 or more and 500 or less. It is preferred that an α-phase and a β-phase are contained as crystal structures, and an area ratio occupied by the α-phase in a cross section is 70% or more and 99.8% or less. It is also preferred that in an X-ray diffraction spectrum obtained by X-ray diffractometry, the value of a peak reflection intensity by the plane orientation (110) of the β-phase is 5% or more and 60% or less of the value of a peak reflection intensity by the plane orientation (100) of the α-phase. It is also preferred that particles composed mainly of titanium oxide are included.

    摘要： A method for producing a composition for injection molding which contains an inorganic powder composed of at least one of a metal material and a ceramic material and a binder containing a polyacetal-based resin and a glycidyl group-containing polymer. The method includes: cryogenically grinding a first resin containing the polyacetal-based resin as a main component; cryogenically grinding a second resin containing the glycidyl group-containing polymer as a main component; mixing a powder obtained by grinding the first resin, a powder obtained by grinding the second resin, and the inorganic powder, thereby obtaining a mixed powder; and kneading the mixed powder.
