Ferro Phosphorus is an important metal material.
ferro phosphorus definition and composition
Ferro-phosphorus is an alloy obtained from phosphorus-making electric furnaces, and its main component is a compound of iron and phosphorus, usually containing 20-26% phosphorus and 0.1-6% silicon. It may also contain other elements, such as carbon, etc., and is a phosphorus-containing iron-based alloy.
ferro phosphorus physical properties
Appearance: Iron phosphorus is a gray, slightly shiny alloy.
Density: Its density ranges from about 5.66.5g/cm³, and there are also claims that its relative density is 5.66.0.
Melting point: The melting temperature range of ferro-phosphorus is usually 1100~1250°C, and there are also claims that its melting point is about 1149°C.
ferro phosphorus chemical properties
Stability: at room temperature, the chemical composition of iron phosphorus is stable, insoluble in acid.
Non-magnetic: iron phosphate is non-magnetic at room temperature.
Surface finish: iron phosphate has a good surface finish.
ferro phosphorus production
Iron phosphorus is prepared by artificial smelting. The main raw materials for smelting ferro-phosphorus include iron ore containing phosphorus, coke (for reduction and providing heat), silica (for adjusting the composition and slagging) and so on. These raw materials are smelted in a high-temperature smelting furnace, where the elements of iron, phosphorus and carbon in the ore are reduced and alloyed to form a ferro-phosphorus alloy. Afterwards, the melted ferro-phosphorus alloy will be cast into blocks or granules of the required shape.
ferro phosphorus uses
Ferro-phosphorus is widely used in many fields:
Metallurgical industry: Ferro-phosphorus is used as an alloying agent in the steelmaking industry, which can change the corrosion resistance and chip resistance of steel. Meanwhile, ferro-phosphorus is also used in desulfurization and dephosphorization processes in steel production to improve the performance and quality of steel. It is widely used in rolls, automobile cylinder liners, engine rollers and large castings to increase the corrosion and wear resistance of mechanical parts.
Chemical industry: iron phosphate can also be used in the production of phosphate and other chemical products.
Other fields: iron phosphate can also be used in atomic energy, building materials, explosives, petroleum and other industries. In addition, after iron phosphorus is ground into ultrafine powder, it can also be used as coating instead of ultrafine zinc powder. At the same time, ferrophosphorus is also a protective substance for radioactive radiation.
