Abstract: A highly electrically conductive composite electrode is provided which comprises an inner layer of an electrically conductive metal, a first outer layer of pressed and sintered powdered titanium metallurgically bonded thereto and a second outer layer of porous sintered powdered titanium bonded to the surface of the first outer layer, the first outer layer of powdered titanium being compacted to a degree sufficient to render it essentially impermeable to aqueous brine and the surface of the second outer layer having an apparent density of from about 30 to about 90 percent.

Abstract: A sintered porous metal article is provided which is essentially thermally stable at elevated temperatures. In addition, a method for producing such an article is also provided which method comprises preparing a blend of base metal particles and active dispersoid particles, forming the mixture into an article of the desired shape, and heating the so-formed article at sintering temperatures.
