How is iron carbide Fe3C powder produced?

Overview of iron carbide Fe3C powder

Iron carbide Fe3C. It is called metal cementite in metallurgy. It is a gray-black crystalline powder with a relative density of 7.694 and a melting point of 1837°C. Insoluble in water, soluble in acid. In an orthorhombic crystal, each carbon atom is surrounded by six iron atoms at the top corners to form an octahedral structure. Each iron atom is shared by two octahedrons, that is, the coordination number of carbon atoms is 6, and the coordination number of iron atoms is 6. The coordination number is 2.

Cementite is also called iron carbide. In the white cast iron box, cementite is formed directly from the melt. For carbon steel, it can be formed by austenite cooling or martensite tempering. As mentioned earlier, cementite is composed of 7 percent carbon. Therefore, in the iron-carbon phase system, the alloy is not cast iron or steel, because all its available iron content is in cementite. In some cases, cementite combines with ferrite (a by-product of austenite) to form bainite and pearlite or a layered structure. Because cementite tends to be thermodynamically unstable, it will eventually transform into graphite and ferrite.

Iron carbide is an inorganic substance with a chemical formula of Fe3C. It is called cementite in metallurgy. 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 located at the top corners, forming an octahedral structure. Each iron atom is shared by two octahedrons, that is, the carbon atoms are coordinated. The number is 6, and the coordination number of the iron atom is 2. The ratio of the number of iron and carbon atoms in the chemical formula is Fe:C= 1/2×6:1=3:1. Iron carbide is an interstitial compound formed at high temperature. There is a strong bonding force between carbon and iron, and the performance is hard and brittle.

Iron carbide Fe3C powder application

The main purpose of iron carbide is to be used as a metal raw material in the steelmaking process to replace molten iron and directly reduce iron or steel scrap. Iron carbide is an intermetallic compound of iron and carbon. More precisely, because the transition metal carbide is immersed in the sodium chloride solution, the corrosion resistance of the substrate is greatly improved, so its role in metallurgy has been widely recognized by industries all over the world. Carburizing plays a vital role in metallurgy. When immersed in 1%-3% sodium chloride solution, its corrosion resistance is significantly improved.

Iron carbide is an interstitial compound formed at high temperatures, and has a strong bonding force between carbon and iron, and is hard and brittle. If the carbon in pig iron is mainly in the form of iron carbide, the cross section of pig iron is silvery white. It is called white iron and is usually 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 called "gray iron". Gray iron has excellent cutting performance and is widely used in machine manufacturing.
