Mechanisms for the SiCl/sup 4//Na and SiF/sup 4//Na reaction systems were examined. Reaction schemes which include 25 elementary reactions were formulated for each system and run to test the sensitivity of the computed concentration and temperature profiles to the values given estimated rate coefficients. It was found that, for SiCl/sup 4//Na, the rate of production of free Si is largely mixing-limited for reasonable rate coefficient estimates. For the SiF/sup 4//Na system the results indicate that the endothermicities of many of the reactions involved in producing Si from SiF/sup 4//Na cause this system to be chemistry-limited rather than mixing-limited.
