Abstract
A catalytic process for converting silicon tetrachloride (STC) into trichlorosilane (TCS) utilizes a metal catalyst such as metal silicide at a low temperature such as 500 C, where the STC is reacted with hydrogen gas in the presence of catalyst and under non-thermal equilibrium conditions, to provide for a product gas stream that includes TCS at levels exceeding those obtained at thermal equilibrium, as well as optionally including HCl and unreacted STC.
