The thermodynamic data of atmospheric pressure were calculated by using HSC chemistry 6.0 software, and the thermodynamic conditions were discussed theoretically.It indicated that the simultaneous reduction of alumina and silicon oxide by carbon at high temperature was beneficial to reduce SiC and Al4C3 in the products.It is feasible to prepare Si-Al alloy by carbon reduction coal fly ash from thermodynamic analysis.The thermodynamic equilibrium components of carbon reduction coal fly ash were simulated by using Equilibrium Composition module, and it was considered that most of the reactions occurred during the reaction were the coupling of two or more reactions, rather than one by one.The preparation of Si-Al alloy by carbon reduction coal fly ash is viable. In order to improve the yield of silicon and aluminum, the method of heating rapidly can be used to avoid the formation of carbide, thereby reducing the content of Al2O and SiO in the equilibrium composition.
