P. M. Parthangal, Richard E. Cavicchi, Michael R. Zachariah
… metal alloys, and conductive ceramics using a bimetallic iron/alumina composite catalyst at low temperatures (550 ?C to 700 ?C). We believe the addition of alumina to the iron catalyst significantly reduces catalyst-metal underlayer … on metals. The alumina also minimizes surface diffusion of iron and allows the formation of a high density of uniformly …
