Iron Carbide Fe3C Powder Properties
About Iron Carbide Fe3C Powder:
Iron carbide is an inorganic substance. Iron carbide chemical formula is Fe3C. It is a compound of iron and carbon, more specifically, an intermediate transition metal carbide with transition formula Fe3C. By weight, it is 6.67% carbon and 93.3% iron. It is called cementite in metallurgy. Iron carbide 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. Iron carbide is an interstitial compound formed at high temperatures. There is a strong bonding force between carbon and iron, and the performance is hard and brittle.
Iron carbide is a hard, fragile material, usually classified as ceramic in its pure form, and is an important component often found in ferrous metallurgy. Although cementite is present in most steel and cast iron, it is produced as a raw material for the iron carbide process and belongs to the family of alternative ironmaking technologies. The name cementite, theoretically, the structure of solidified steel consists of a kind of cell tissue, with ferrite as the nucleus and Fe3C as the cell envelope.

Properties 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. Do not dissolve in water, soluble in acid. In orthogonal crystals, each carbon atom is surrounded by six iron atoms located at the apex angle, forming an octahedral structure, each iron atom is shared by two octahedrons, that is, the coordination number of carbon atoms is 6, iron The atomic coordination number is 2. The ratio of iron to carbon atoms in the chemical formula is Fe: C = 1/2 × 6: 1 = 3:1.

How is Iron Carbide Fe3C Powder produced?
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% 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 is eventually transformed into graphite and ferrite.
Application of Iron Carbide Fe3C Powder:
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 scrap steel. Iron carbide is an intermetallic compound of iron and carbon. More precisely, the intermediate transition metal carbide greatly enhances the corrosion resistance of the substrate due to its immersion in the sodium chloride solution, so its role in metallurgy has been widely recognized by industries all over the world. Cementite 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 is decomposed 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.
