· Fe2P

Fe2P is an iron phosphide intermetallic compound that combines iron with phosphorus in a fixed stoichiometric ratio. While not a commodity engineering material, Fe2P and related iron phosphides are of growing interest in catalysis, energy storage, and functional materials research, where they offer unique electronic and magnetic properties distinct from pure iron or conventional iron alloys. The material is primarily explored in academic and advanced industrial settings rather than traditional structural applications, with particular attention to electrocatalytic performance in hydrogen evolution and oxygen reduction reactions.
