Abstract (en)

[origin: EP3766601A1] To provide titanium-based powder in which the pores in titanium powder are reduced. A titanium-based powder having a ratio of a pore area obtained by dividing a cross-sectional area of pores in a cross-section of the titanium-based powder by an area of the cross-section of the titanium-based powder is 0.3% or less. A method for producing a titanium-based powder includes a Hydrogenation-DeHydrogenation method including a hydrogenation process, a pulverization process, and a dehydrogenation process using a titanium-based raw material is provided. A concentration of total MgCl<sub>2</sub> contained in the titanium-based raw material is 1.0 mass% or less, and a concentration of internal MgCl<sub>2</sub> contained in the titanium-based raw material is 0.1 mass% or less.
