Aluminium carbide is prepared by direct reaction of aluminium and carbon in an electric arc furnace. [3] 4 Al + 3 C → Al 4 C 3. An alternative reaction begins with alumina, but it is less favorable because of generation of carbon monoxide. 2 Al 2 O 3 + 9 C → Al 4 C 3 + 6 CO. Silicon carbide also reacts with aluminium to yield Al 4 C 3.
In chemistry, a carbide usually describes a compound composed of carbon and a metal. ... Three examples are aluminium carbide Al 4 C 3, magnesium carbide Mg 2 C [9] ...

In primary aluminium production, aluminium carbides (Al 4 C 3) originates from the reduction of alumina where carbon anodes and cathodes are in contact with the mix. Later in the process, any carbon tools in contact with the liquid aluminium can react and create carbides.
AlSiC, pronounced "alsick", [1] is a metal matrix composite consisting of aluminium matrix with silicon carbide particles. It has high thermal conductivity (180–200 W/m K), and its thermal expansion can be adjusted to match other materials, e.g. silicon and gallium arsenide chips and various ceramics.
