Abstract
A method for producing titanium powder containing a solid-soluted oxygen comprises the steps of: heating titanium powder comprised of titanium particles in an oxygen-containing atmosphere in a temperature range of 160° or higher and less than 600° C. to form a titanium oxide layer on the surface of the titanium particle; and heating the titanium powder having the titanium oxide layer in an oxygen-free atmosphere in a temperature range of 450° C. or higher and a melting point of the titanium oxide layer or lower to decompose the titanium oxide layer on the surface of the titanium particle so that oxygen atoms dissociated form a solid solution in a matrix of the titanium particle.
