ABSTRACT:
A process for the manufacture of sintered metal bodies, comprising the steps of providing a mixture of a powdered metal or alloy and at least one pore-forming filler which is a fine grained salt, vaporizable at the sintering temperature of the metal or alloy, heating the mixture to the sintering temperature of the metal or alloy under vacuum, whereby the filler vaporizes from the metal to leave the porous sintered metal body behind, and recovering the porous sintered metal body is disclosed. The sintered metal bodies are particularly useful for production of battery electrodes.
