Iron(I) phosphide is an inorganic compound of iron and phosphorus with the chemical formula Fe3P.[2][3]
Fe3P occurs naturally as a mineral called schreibersite in some meteorites. Some iron may be replaced by nickel.[4]
Synthesis
[edit]Iron(I) phosphide can be prepared by the chemical reaction of iron and phosphorus at high temperature.[5]
- 3Fe + P → Fe3P
Physical properties
[edit]The compound forms gray to blue-gray crystals of a tetragonal system, space group I4.[4]
It is insoluble in water.[6] Soluble in nitric acid, HF, aqua regia.[7]
Fe3P decomposes on melting.[4]
Chemical properties
[edit]Iron(I) phosphide reacts with moisture and acids to produce phosphine PH3, a toxic, self-igniting gas.[8]
Uses
[edit]The compound is a semiconductor widely used in high-power and high-frequency applications, such as laser diodes.[9][dubious – discuss]
