Abstract:
A process for producing a low-oxygen metal powder, comprising passing a raw metal powder coated by hot melting of a hydrocarbon organic compound through thermal plasma flame composed mainly of an inert gas so as to reduce the content of oxygen in the raw metal powder. Preferably, the obtained metal powder is subjected to heat treatment in vacuum or hydrogen atmosphere. Preferred example of the hydrocarbon organic compound is stearic acid.
