What are the application areas of aluminum carbide Al4C3 powder?

Aluminum carbide (English name: Aluminium carbide), an inorganic compound, the molecular formula is Al4C3, the molecular weight is 143.96, yellow or green-gray crystalline block or powder, hygroscopic. High temperature decomposition, hydrolyzed into methane and aluminum hydroxide in cold water. For metallurgy and catalyst. By the reaction of alumina and coke obtained.

How to prepare aluminum carbide

It is obtained by heating alumina and coke in an electric furnace.

Aluminum carbide Al4C3 is prepared by direct compounding of two elements at high temperature.

First prepare a mixture of 1 part heavy smoke black and 6 parts heavy aluminum powder, moisten the mixture with pine essential oil, place a tight layer in a clay crucible, and lay a layer of toner on top. The crucible should be covered with a lid and all crevices covered with refractory clay mixed with asbestos fibers. Then, after pre-drying the crucible containing the mixture in an oven, the mixture is fired at a temperature not lower than 1200° C. for 30 minutes. Higher temperatures allow the reaction to proceed better. After cooling the product is treated with dilute hydrochloric acid (or base solution) under cooling to remove excess aluminum. The aluminum carbide prepared as fine crystalline powder is washed with water to remove aluminum chloride, and then the water is quickly washed away with alcohol, and the product is dried in a drying oven at a temperature of 80-90°C. The product contains a large amount of aluminum nitride.

Pure aluminum carbide is colorless, but the products obtained by the above method often have different colors due to impurities in the raw materials.

When calcined in hydrogen in a mixture of calculated amounts of aluminum and soot, a pure product without aluminum nitride can be produced. This calcination is carried out at a temperature of 1800-1900°C for 2-3 hours. The resulting product is ground and calcined once more at the above-mentioned temperature

Overview of aluminum carbide Al4C3 powder

Aluminum carbide Al4C3 powder is an inorganic compound with the molecular formula Al4C3. Yellow or green-gray crystal block or powder, hygroscopic. Decomposes at high temperature and decomposes into methane and aluminum hydroxide in cold water. Al4C3 has a hexagonal crystal structure. Aluminum carbide chemical formula Al4C3 is a carbide of aluminum. Appearance is pale yellow to brown crystals. Stable at temperatures up to 1400°C. Decomposes in water to form methane.

Aluminum carbide Al4C3 powder has an unusual crystal structure consisting of alternating layers of Al2C and Al2C2. Each aluminum atom is matched with 4 carbon atoms to form a tetrahedral arrangement. Carbon atoms exist in two different binding environments. One is a deformed octahedron with 6 Al atoms at 217 pm. The other is a twisted triangular bipyramid structure with 4 Al atoms at 190-194 pm and a fifth Al atom at 221 pm.

Aluminum carbide Al4C3 powder application

Aluminum carbide Al4C3 powder is used in metallurgy, catalysts and methane production. Additionally, typical applications for aluminum carbide include:

1. Aluminum carbide particles finely dispersed in an aluminum matrix can reduce the creep tendency of the material, especially when used in combination with silicon carbide particles.

2. Aluminum-aluminum carbide composites can be made by mechanical alloying, grinding together aluminum powder and graphite particles.

3. Aluminum carbide can be used as abrasive for high-speed cutting tools, and its hardness is almost the same as topaz.

4. Aluminum carbide is also used in fireworks, for example, to achieve the effect of fireflies.
