The main components of ferrophosphorus are phosphorus and iron. The phosphorus content is usually between 20% and 26%, and the silicon content is between 0.1% and 6%. In addition, it also contains trace amounts of manganese, carbon, sulfur and other elements. Ferrophosphorus is relatively hard and brittle and is difficult to process. It is generally sold in the form of natural blocks. Its melting temperature ranges from 1100 to 1250°C, and its density is 5.8 to 6.5 g/cm³.

Generally, phosphorus is regarded as a harmful impurity in steel because it reduces the plasticity and toughness of steel and increases the brittleness of steel. However, in some special steel types, adding an appropriate amount of phosphorus can improve the hardness, wear resistance and processability of the steel. For example, wear-resistant cast iron contains about 0.15% phosphorus, which can significantly improve its wear resistance; train brake shoes contain 0.7% to 1.0% phosphorus, which can improve its wear resistance and thermal conductivity. At high temperatures, ferrophosphorus has reducing properties and can react with oxygen, so it is often used as a deoxidizer. It can reduce some oxides in the steelmaking process to metals, thereby reducing the oxygen content in the steel and improving the quality of the steel.

Ferrophosphate also plays an important role in the foundry industry. Adding phosphorus to cast iron castings can improve the fluidity of molten iron, thereby improving casting performance and surface quality. For example, gray cast iron containing 0.5% phosphorus can significantly improve its tensile strength; wear-resistant cast iron containing about 0.15% phosphorus can significantly improve its wear resistance. In addition, phosphorus iron is also widely used in rolls, automobile cylinder liners, engine rollers and large castings to increase the corrosion resistance and wear resistance of mechanical parts. Ferrophosphorus also has certain application value in the fields of electronic products and chemical reagents. In electronic products, ferrophosphorus is often used as a material for electronic components and a dopant in semiconductor production. In chemical reagents, ferrophosphorus is an important raw material for the preparation of other chemical reagents.

In addition, ferrophosphorus can also be used as a protective material against radioactive radiation. In some special cases, ferrophosphorus also has other special uses, such as ferrophosphorus containing 20% ​​phosphorus ground into ultrafine powder can replace ultrafine zinc powder as coating, etc. In summary, ferrophosphorus, as an important ferroalloy material, has a wide range of application value in the steelmaking industry and other fields. By reasonably controlling the addition amount of ferrophosphorus and smelting process parameters, the improvement effect of ferrophosphorus on steel properties can be fully exerted.
