Title:
金属多孔質体の製造方法
Document Type and Number:
Japanese Patent JP4235813
Kind Code:
B2
Abstract:
The present invention provides a process for producing a porous metal body, the process comprising: 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. According to the process of the present invention, 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.
