Iron Carbide Fe3C Powder Properties

About Iron Carbide Fe3C Powder:
Iron carbide is an inorganic substance. Iron carbide's chemical formula is Fe3C. It is a compound of iron and carbon, 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 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 six iron atoms at the top corners, forming an octahedral structure. Two octahedrons share each iron atom. 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. Carbon and iron have a strong bonding force, 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. It belongs to the family of alternative ironmaking technologies. Theoretically, the name cementite structure of solidified steel consists of a kind of cell tissue, with ferrite as the nucleus and Fe3C as the cell envelope.

How is Iron Carbide Fe3C Powder produced?
Carbothermal reduction method
Carbon thermal reduction is a commonly used method for preparing iron carbide, which is to react coke or graphite with iron oxide in an oxygen-free or weakly oxidizing atmosphere under high-temperature conditions. The reaction equation of this method is:
Fe2O3(s)+ 3C(s) → 2Fe3C(s)
The reaction must be carried out at high temperatures, so it must be heated using a high-temperature furnace. At the same time, the atmosphere in the reaction will affect the formation of iron carbide; if there is a lot of oxygen, it will generate iron trioxide. Therefore, to prepare iron carbide with higher purity, it is necessary to strictly control the reaction conditions.
Electrothermal method
An electrothermal method uses electric energy to produce high 0temperature so that an iron oxide reduction reaction produces iron carbide. In the electrothermal method, graphite is usually used as the electrode so that the iron oxide on the surface of the graphite electrode electrochemical reduction reaction produces iron carbide. The reaction equation of this method is:
Fe2O3(s) + 3/2C(s) + 3/2O2(g) → 2Fe3C(s) + 3/2CO2(g)
The advantage of the electrothermal method is that it can directly use electrical energy to produce high temperatures, so the temperature and reaction time can be easily controlled. At the same time, because the reaction is carried out on the electrode surface, high-purity iron carbide can be obtained. However, the cost is higher due to the need to use a lot of electricity.
Vapor deposition method
Vapor deposition is a method of depositing iron carbide on the surface of a matrix by chemical reaction or physical deposition. This method usually uses gases such as methane, hydrogen, and nitrogen as raw materials to chemically react with iron oxide under high temperatures and pressure to generate iron carbide and deposit it on the surface of the matrix. The reaction equation of this method is:
Fe2O3(s)+ 3CH4(g) → 2Fe3C(s)+ 9H2O(g)
The benefit of the vapor deposition method is that the iron carbide layer can be directly deposited on the surface of the substrate, so high purity and high-density iron carbide coating can be obtained. At the same time, the cost is low because there is no need to use a lot of electricity. However, the equipment investment is large due to the need to use high-temperature and high-pressure equipment.
Plasma method
The plasma method is a material preparation method using the high temperature and high-speed characteristics of plasma. In the plasma method, gases such as hydrogen, nitrogen, and methane are usually used as raw materials to ionize and accelerate the bombardment to the substrate surface through the high temperature and high-speed characteristics of the plasma so that the reduction reaction of iron oxide generates iron carbide. The reaction equation of this method is:
Fe2O3(s)+ 3/2CH4(g) → 2Fe3C(s)+ 3H2O(g)
The advantage of the plasma method is that the iron carbide coating can be directly formed on the substrate surface, so high purity and high-density iron carbide coating can be obtained. At the same time, because the temperature and speed of the plasma are adjustable, the coating's reaction conditions and thickness can be easily controlled. However, the equipment investment is large due to the need to use large plasma generators, high-precision control systems, and other equipment.

Application of Iron Carbide Fe3C Powder:
Wear-resistant material
Iron carbide has high hardness and wear resistance and can be widely used as a wear-resistant material in various mechanical parts and tools. For example, the use of iron carbide on the bucket of an excavator can improve its wear resistance and service life. In addition, iron carbide can also be used to manufacture precision tools such as cutting tools, drills, and measuring tools to improve their hardness and wear resistance.
Cemented carbide
Iron carbide is an important part of cemented carbide that can be mixed with cobalt, chromium, and other metals to make a variety of cemented carbides with high hardness, high strength, high wear resistance, and other advantages. Iron carbide carbide is widely used in manufacturing to process high-temperature alloys, stainless steel, and other difficult materials to improve its processing efficiency and product quality.
Powder smelting
Powder smelting is a method of melting and solidification by heating metal powder or metal oxide powder above the melting point. In powder smelting, iron carbide can be added as an additive to metal powder to improve its hardness and wear resistance. For example, a certain amount of iron carbide can be added to improve its wear resistance and hardness in the manufacture of high-speed steel.
Electronics industry
Iron carbide can be used in the electronics industry to manufacture precision electronic components such as integrated circuit chips and magnetic memory devices. Because of its high hardness, high density, and high wear resistance, iron carbide can be used as an electrode and conductive material in electronic devices to improve its performance and stability.
Other applications
Iron carbide can also be used in other fields.
