This report details the thermodynamic analysis on zinc reduction of silicon tetrachloride. The diagrams of △_r(G_m)~Θ-T and (K_p)~Θ-T for the Zinc production reaction were plotted. The reasonable temperature range was obtained by the thermodynamic analysis. The theoretical basis of improvements of the equipment and process flow were provided by the thermodynamic analysis. The continuous processing, low Energy consumption and the shortening of process flow were the advantage in the improvement of equipment and process.
