What is Aluminium Carbide?
Aluminium carbide also known as aluminum tetracarbide with the molecular formula Al4C3, and is a form of aluminium carbonide. It is an ionic, translucent, hard, yellowish brown, transparent rhombic hexagonal crystal. At room temperature it doesn’t conduct electricity and has a complex crystal structure. It is possible to have 4,5-6 coordinated metal atoms within the system. The lengths of Al-C bonds are 1.90-2.22A while the C-C-bonds that are the shortest and 3.16A respectively. A single carbon atom was found in the structure, in the discrete negative ion C-4. It is not like acetylene.

Method of synthesizing aluminium carbide
Al4C3 may be prepared by simply combining two simple substances at very high temperatures. Make a mixture from 1 part black smoke and 6 parts heavy aluminium powder. After moistening the mix with pine oils, lay down a thick layer of clay in a crucible and then add carbon powder. You should cover the crucible by a lid and then fill any gaps with refractory or asbestos clay. Place the mixture-filled crucible in an oven for pre drying. For 30 min, heat the mixture to 1200F. You can improve the result by heating it up. Cool the product under cool water to get rid of excess aluminum. Aluminium carbide is a finely crystalline powder that can be washed in water. After this, alcohol should quickly be used to wash away the excess aluminium. At 8090, the product can be dried in a drying oven. It contains large amounts of aluminium oxide. The pure aluminium carbide product is inert, however the colours of the products created by this method are often different due to the impurities present in raw materials. Pure aluminium carbide can also be produced if the soot-alluminium mixture is calcined with hydrogen. For 2 hours, the calcination should be performed at 1800-1900. You must grind the product and then calcinate it again at the same temperature.

Principal uses for aluminium carbide
Aluminium carbide is used often to improve the strength and durability of ternary aluminum-based materials (Al-Si AlC or Al Ali AlC). AlC is also an important compound for the technical sector of the metal-alluminium industry. It can be used to reduce metal oxides within the metallurgical sector, or chemical reaction catalysts for the chemical industry. Also, it is useful in advanced ceramic materials, such as cutting- and mouldmaking in ceramics. Chemicalbook, an ionic chemical, has carbon atoms that exist as C by themselves in its lattice structure. C is strong in alkalinity. Hydrolysis produces methane via C+4H–CH. AlC is also a methane dryer and generator. AlC’s rhombic Hexahedron is also a combination of AlC and AlC layers. The unique structure of AlC nanowires makes them a possibility cold electron emitter.

Aluminum carbide Price
Price will depend on how pure and small the aluminium carbide particles are. The purchase volume may also have an effect on cost. Large quantities of high quality aluminium carbide are more expensive. On our official website, you can see the price for aluminium carbide.
