POROUS METAL POWDER AND METHOD FOR PRODUCTION THEREOF
摘要
A method for producing a porous metal powder comprising subjecting a starting metal to an oxidation treatment and then to a reduction treatment, characterized in that the starting metal is oxidized in the presence of chlorine and/or a chloride. Massive metal bodies formed after reduction comprise pillar-shaped particles being entangled in one another as are rootstocks, and thus, the metal powder has open pores.
