description of ferro phosphorus
Ferrophosphorus is an alloy of iron and phosphorus. This ferroalloy contains high proportions of Iron Phosphides, Fe₂P, and Fe₃P. Ferrophosphorus is used in many industrial applications, and it is becoming increasingly popular in the manufacture of steel as the addition of it increases the steel's corrosion resistance and strength. It also works as a deoxidizing agent. Ferrophosphorus enhances molten iron's fluidity, improving iron alloys' casting performance.
properties of Ferrophosphorus
Ferrophosphorus is in the form of a gray-black or dark gray solid, has a high density, has a certain sense of weight, and is not easy to volatilize and dissolve in water at room temperature.

Use of Ferrophosphorus
The addition of ferrophosphorus is used to produce powder metallurgy (P/M) steels with favorable magnetic properties, e.g. high saturation induction. Iron phosphide acts here as a solid solution hardener and a sintering aid. Usually, about 0.45 w/o of phosphorus is added to the iron; a higher amount can improve magnetic properties but above about 0.8 w/o the process parameters have to be too tightly controlled to prevent phosphorus segregation on grain boundaries and resulting excessive brittleness.
manufacture of Ferrophosphorus
Ferrophosphorus is produced by reducing apatite with carbon at high temperatures. Silica is added to form calcium silicate. Add steel scraps and restore the original apatite. Silica is added to form calcium silicate. Add steel scraps and reduced phosphorus to generate Fe2P.
