Abstract

Sintered porous electrodes are made from a powder mixture of a catalytically active metal such as Fe, Ni, Co, Mo, W, Ag and an alkali soluble metal or metalloid such as Al, Mg, Zn or Si, the compacted mixture being sintered at 10-150 DEG C. below the melting point of the lower melting constituent and the major part of the alkali soluble constituent is then leached with an alkali. The powder mixture should contain at least 50% by weight of the active metal, 10-30% of the alkali soluble metal and optionally 30% of ammonium carbonate or bicarbonate as a pore former. Several examples of the process are given quoting powder particle sizes, pressures and temperatures.
