Abstract

The thermodynamics of the reactions for carbon reducing of coal fly ash to Si-Al alloy were investigated with HSC Chemistry 6.0 thermodynamic analysis software.The standard molar enthalpy change, Gibbs free energy and equilibrium constant of the reaction system at different temperatures were calculated. The relationship between the thermodynamic parameters and the temperature were analyzed.The results showed that the rapid increasing of the reaction temperature and avoiding residence time of reactants in low temperature were conducive for the formation of Si-Al alloy.The results provided a theoretical basis and basic data for the preparation of Si-Al alloy with carbon reduction coal fly ash.
