Iron Carbide Fe3C Pulver


Iron carbide

An inorganic substance.

Iron carbide

Formula chemical

Is Fe3C. It is composed of iron and carbon. More specifically it is an intermediate metal carbide with Fe3C transition formula. It weighs 6.67% and 93% respectively. It’s also known as cementite in metalurgical.

Iron carbide is

An off-white, crystalline powder of 7.694, with a melting temperature of 1250degC and relative density of 7.694. Water insoluble, acid soluble. Orthorhombic crystals are made of iron carbide. An octahedral crystal is formed when each carbon atom surrounds 6 iron atoms at its top corners. The iron atoms of each iron are shared by 2 octahedrons. This means they can be coordinated. It is 6 and its coordination number is 2. An interstitial compound made at high temperatures is iron carbide. It has a strong bonding power between iron and carbon, making it tough and brittle.

Iron carbide

This is a soft, fragile and hardy material. In its purest form it is usually considered ceramic. While cementite is found in many steels and cast iron, the raw material used to make iron carbide is it. It is also part of the group of alternate ironmaking techniques. According to theory, cementite refers to a form of cell tissue with Fe3C and ferrite in the nucleus.

Iron Carbide Fe3C Pulp – Properties

Iron carbide Fe3C. This is what metal cementite is. It’s a gray-black, crystalline powder having a relative densit of 7.694 mol/l and a melting point at 1837 °C. Not to dissolve in water. It can be dissolved in acids. Orthogonal crystals contain six iron atoms surrounding each carbon atom. These six iron atoms form an octahedral structural. Each iron atom is also shared by two other octahedrons. The coordination number of the carbon atoms in this structure is 6. Fe is the ratio of carbon and iron atoms as shown in the chemical formula. It’s C = 1/2×6: 1 = 3.

How does Iron Carbide Fe3C Pulver get made?

Iron carbide can also be called cementite. Cementite, which is found in the white cast iron box, can be directly melted from its melt. Carbon steel can be produced by either austenite tempering or martensite cooling. The cementite content is 7% carbon. Iron-carbon phases do not include cast iron and steel. All iron in the alloy comes from cementite. Cementite can be combined with ferrite as a by-product from austenite to make bainite, pearlite or other layered structures. It is often thermodynamically unreliable and can be transformed to graphite, ferrite or other forms.

Iron Carbide Fe3C Pulp


Iron carbide serves two main purposes. It is used to produce steel by being a raw metal in the steelmaking process. Iron carbide, an intermetallic combination of carbon and iron, is a compound that contains both carbon and iron. In other words, iron carbide is an intermetallic compound of carbon and iron. Because it absorbs sodium chloride solution in its form, its importance in metallurgy was widely recognised by all industries. Cementite plays an essential role in metallurgy. Cementite’s resistance to corrosion is greatly improved when it’s immersed into 1%-3% sodium salt solution.

Iron carbide can be formed at high temperatures as an interstitial substance. It has a strong binding force between iron and carbon. Silvery-white is the result of high levels of carbon found in pig iron. White iron is a common raw material in steelmaking. When the iron carbide found in the Pig iron is broken down into graphite, it forms a grey cross-section known as “gray iron”. It is widely used for machine manufacturing because of its excellent cutting ability.
