ABSTRACT:
Disclosed is a process of producing a porous metal body containing a metal component which is likely to be oxidized, by which process the amounts of residual carbon and residual oxygen therein are decreased, and by which the performance of the product porous body can be largely promoted. The process for producing a porous metal body by sintering a material of the porous metal body, which material is obtained by coating a slurry containing a metal powder and an organic binder on an organic porous aggregate, comprises a defatting step of treating the material of the porous metal body at a temperature not higher than 650° C. in an atmosphere containing carbon monoxide and carbon dioxide; a decarbonization step of treating the material of the porous metal body after the defatting step in an inert atmosphere or vacuum atmosphere at a temperature not higher than sintering temperature; and a sintering step of retaining the material of the porous metal body after the decarbonization step in an inert atmosphere, vacuum atmosphere, hydrogen atmosphere, or in a reducing atmosphere containing hydrogen gas and an inert gas at a temperature not higher than the melting point of the metal powder.
