Ferrophosphorus / Iron Phosphide Powder

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.
Typical Applications

Ferrophosphorous has a variety of uses. Steel producers use it as a deoxidizing, dehydrating, and drying agent. Other uses are in the production of high-strength special steels with low alloy content (HSLA) and the production of phosphorous castings. The chemical industry uses ferrophosphorus and soda ash to create sodium dihydrogen phosphate and trisodium phosphate.

Packaging Options

Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers.
