Iron phosphide explained

Iron phosphide is a chemical compound of iron and phosphorus, with a formula of FeP.< Its physical appearance is grey needles.

Manufacturing of iron phosphide takes place at elevated temperatures, where the elements combine directly. Iron phosphide reacts with moisture and acids producing phosphine (PH₃), a toxic and pyrophoric gas.

Iron phosphide is a good electric and heat conductor.^[1]

Below a Néel temperature of about 119 K, FeP takes on an helimagnetic structure.^[2]
