Triferro phosphide

Triferro phosphide, Fe3P, occurs as crystals embedded in a eutectic mixture of this phosphide and iron when phosphorus and iron containing more than 84 4 per cent, of iron are fused together. Its density is 6 74, and melting-point 1110 ° C. It dissolves in concentrated aqueous hydrogen chloride, evolving pure hydrogen. Thus —3... 

Triferro phosphide has been found in a cavity of pig iron from a blast furnace near Middlesbrough, in the form of small tin-white needles,... 

In addition to the foregoing, several other phosphides have been described, but the evidence in favour of these being separate chemical entities is not so convincing.10 Hose believed that he had prepared triferro tetraphosphide, Fe3P4, by the action of hydrogen phosphide upon pyrites —...
