Iron phosphide is a chemical compound of iron and phosphorus, with a formula of FeP.<[1] Its physical appearance is grey needles.
Manufacturing of iron phosphide takes place at elevated temperatures, where the elements combine directly.[1] Iron phosphide reacts with moisture and acids producing phosphine (PH3), a toxic and pyrophoric gas.
Iron phosphide is a good electric and heat conductor.[2]
