Aluminum Carbide: What’s it all about?

Three-carbon four-aluminum is also known by the molecular formula AL4C3, and it’s a form of aluminum carbide. It’s a transparent, light-yellow-brown, hard and hard rhombohedral, crystal. It is an ionic crystalline and doesn’t conduct electricity at room temperatures.

Aluminum Carbide

Calcium carbide can contain a little aluminum carbide. Metal aluminum can be melted using electrolysis. Graphite electrodes may become corroded to get a little aluminum carbide. Aluminium carbide can be found in many metal matrix composites. Aluminum matrix composites with carbon fiber can also react to 500. It can also be blocked by covering it with titanium bore. A silicon carbide reinforced aluminum composite material produces an aluminum carbide layer on the surface of silicon carbide particle. The result of the chemical reaction of silicon carbide with aluminum melt is to reduce the material’s strength. This can be prevented by using either an oxide or nitride that forms a silicon layer on top of silicon carbide particles.

A Synthesis Method for Aluminum Carbide

Al4C3 Aluminum carbide can be made from the combination of two different elements at high heat. Make a mixture from 1 part of heavy smoke black to 6 parts of heavy aluminum powder. Then, add pine essential oils to moisten it. After that, you can place a thin layer of the mixture in a clay container. Add a layer with carbon powder. You should cover the crucible by a lid and then fill in any gaps with refractory soil with asbestos fibers. Next, place the mixture and crucible in an oven. For 30 minutes, heat the mixture at 1200 degrees C. The reaction can proceed more smoothly if it is heated to a higher temperature. To remove any excess aluminum, dilute hydrochloric (or alkaline) acid is applied to the product after cooling. Aluminum carbide as fine, crystalline powder can be washed using water. Next, it is quickly washed off with alcohol and placed in a drying container at 80 to 90 degrees for drying. It contains large amounts of aluminum Nitride.


While pure aluminum carbide can be colorless, products manufactured using the above process often display different colors because of impurities in raw materials. You can obtain a pure aluminum product with no aluminum nitride by calcining the soot and aluminum mixture in hydrogen. The calcination process should take place at 18001900 degrees for two to three hours. Once the product has been ground, it is calcined once more at the above temperatures.
