description of ferro phosphorus
Ferrophosphorus is an alloy of iron and phosphorus. This ferroalloy contains high proportions of Iron Phosphides, Fe₂P, and Fe₃P.
As an important inorganic material, ferrophosphorus has good physical and chemical properties and is widely used in metallurgy, chemical industry, agriculture, and other fields. However, when using iron phosphorus, it is necessary to pay attention to its impact on the environment and the human body to ensure safe use.
properties of Ferrophosphorus
The atomic number of phosphorus is 15, the atomic weight is 30.97, the outer electronic structure is 3S3P, the density is 1.83g/cm3 (white phosphorus) and 2.2g/cm3 (red phosphorus), the melting point is 44°C, and the boiling point is 257°C. There are phosphides such as Fe3P, Fe2P, FeP, and FeP2. The melting temperature range of iron containing 18% to 25% phosphorus is 1100~1250℃, and the density is 5.8~6.5g/cm3.

Use of Ferrophosphorus
Ferrophosphorus reacted with sulfur or pyrite, is used for the production of phosphorus pentasulfide.
Ferrophosphorus can be added to cast iron, where the phosphorus improves fluidity and therefore quality of the castings, which can increase wear resistance and cutability. In steel, its addition to some alloys can improve corrosion resistance.
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.
