<p>An improved method for producing porous materials is provided comprising the steps of preparing a slurry comprising a binder and metal powder, impregnating a foam structure of organic material, curing the impregnated slurry within the foam structure, burning off the foam structure, decarburizing the resulting structure and sintering the resulting porous material product in vacuum. The sintering and decarburizing steps may be performed in a partial pressure atmosphere of reactive gas which will not adversely react with the porous metal product.</p> |
