A note on solid-state reaction kinetics: The formation of silicides from thin films of metallic alloys

The overall kinetics of silicide formation from metal-silicon reactions, like those of most solid state reactions, result from the interactions of specific kinetic effects and thermodynamic terms. The decrease in reaction rate which is observed when Ni-Cr alloys substituted for pure Ni cannot be explained by changes in the thermodynamic driving force. Some alternative suggestions are proposed.
