ABSTRACT:
A process for producing a porous metal body, the process includes melting part of a starting metal material in succession while moving the material by a floating zone melting method under a gas atmosphere to dissolve a gas into a resultant molten metal; and solidifying the molten metal zone in succession by cooling. Even when the starting metal material is of low thermal conductivity, a porous metal body with uniform and micro pores grown only in the longitudinal direction is produced.
