Abstract
Aluminum-silicon alloys are formed by bringing a mix containing sources of alumina, silica and carbon to a temperature in the range of 1500.degree. and 1600.degree. C to form silicon carbide and carbon monoxide. The mix containing the silicon carbide is then brought to a temperature in the range of 1600.degree. to 1900.degree. C to form aluminum oxycarbide and carbon monoxide. Thereafter, the mix containing the silicon carbide and aluminum oxycarbide is brought to a temperature in the range of 1950.degree. to 2200.degree. C to produce an aluminum-silicon alloy.
