1. A method for preparing trichlorosilane comprising
heat treating silicon (Si) and a copper (Cu) compound to a temperature equal to or more than the melting point of the copper compound to form copper silicide (Cu-silicide) on the silicon; and supplying silicon tetrachloride and hydrogen to the silicon where Cu-silicide is formed to conduct a hydrochlorination reaction. |
