What is the use of iron carbide Fe3C powder?

Iron carbide Fe3C powder overview

Iron carbide is an inorganic substance with the chemical formula Fe3C. In metallurgy, it is called cementite. It is an off-white crystalline powder with a relative density of 7.694 and a melting point of 1250°C. Insoluble in water, soluble in acid. Iron carbide is an orthorhombic crystal. Each carbon atom is surrounded by 6 iron atoms at the top corners, forming an octahedral structure.

How is iron carbide Fe3C powder produced?

Cementite is also called iron carbide. In white cast iron boxes, cementite is formed directly from the melt. For carbon steel, it can be formed by austenitic cooling or martensitic tempering. As mentioned earlier, cementite consists of 0.07 carbon. Therefore, in the iron-carbon phase system, the alloy is not cast iron or steel because all its available iron content is in the cementite. In some cases, cementite combines with austenite by-product ferrite to form bainite and pearlite or a layered structure. Because cementite tends to be thermodynamically unstable, it will eventually transform into graphite and ferrite.

Application of iron carbide Fe3C powder

The main use of iron carbide is as a metal raw material to replace molten iron, direct reduced iron or scrap steel in the steelmaking process. Iron carbide is an intermetallic compound of iron and carbon. More precisely, because the immersion of transition metal carbide in sodium chloride solution greatly improves the corrosion resistance of the matrix, its role in metallurgy has been widely recognized by the industrial circles around the world. Carburizing plays a vital role in metallurgy. Soaked in 0.01-0.03 sodium chloride solution, its corrosion resistance is significantly improved.

Iron carbide is an interstitial compound formed at high temperatures, with a strong bond between carbon and iron, making it hard and brittle. If the carbon in the pig iron is mainly in the form of iron carbide, the cross section of the pig iron is silvery white. It is called white iron and is often used as a raw material for steelmaking. If the iron carbide in the pig iron decomposes into graphite in a free state, the pig iron has a gray cross section, which is called "gray iron". Gray cast iron has excellent cutting performance and is widely used in machinery manufacturing.
