Ferrophosphorus is a symbiotic compound of iron and phosphorus, and usually contains a certain amount of trace elements such as silicon (Si) and carbon (C). Its chemical composition is usually expressed as the molecular formula FeP, but in fact the phosphorus content in ferrophosphorus can vary within a certain range. The common phosphorus content of ferrophosphorus is between 15.0% and 26%.

Ferrophosphorus is usually prepared by artificial smelting. In the smelting process, ore containing elements such as iron and phosphorus (such as apatite) is used as raw material, and reducing agents such as coke are added to smelt in a high-temperature smelting furnace. During the smelting process, the iron, phosphorus and other elements in the ore will be reduced and alloyed to form ferrophosphorus alloy. After that, the smelted ferrophosphorus alloy is cast into block or granular products of the desired shape. Ferrophosphorus has some unique physical properties. For example, the melting temperature of ferrophosphorus containing 18% to 25% phosphorus ranges from 1100 to 1250°C and the density is 5.8 to 6.5 g/cm³. In addition, ferrophosphorus is usually hard and brittle, and its brittleness needs to be paid attention to during processing.

In the steelmaking industry, ferrophosphorus is mainly used as a deoxidizer and alloying agent. It can effectively remove oxygen from steel and improve the quality of steel. At the same time, ferrophosphorus can also change the corrosion resistance and chipping resistance of steel, so that the steel has better mechanical properties and processing properties. In the steelmaking process, the amount of ferrophosphorus added needs to be determined according to the specific steel type and process requirements to ensure that the performance of the steel reaches the best state. In the foundry industry, ferrophosphorus can be used as a phosphorus element additive to improve the fluidity of molten iron and the surface quality of castings. The addition of ferrophosphorus can improve the hardness and wear resistance of castings, making them more suitable for occasions that need to withstand high loads and wear. In addition, ferrophosphorus can also be used to produce cast iron parts, such as gray cast iron, ductile iron, etc., to improve the mechanical properties and corrosion resistance of castings. Ferrophosphorus is also widely used in the chemical industry. It can be used as a raw material for the production of chemical products such as phosphates, and is used to manufacture phosphate fertilizers, pesticides, flame retardants, etc. The addition of ferrophosphorus can improve the quality and performance of products and meet the needs of different fields.
