Claim:
1. A method for producing trichlorosilane comprising: a step of providing an apparatus for producing trichlorosilane comprising: a step of introducing metallurgical grade silicon powder to the reactor using the raw material supply device; a step of introducing hydrogen chloride gas to the reactor from below using the gas introduction device; a step of passing the heating medium through the heat transfer tube; a step of reacting the metallurgical grade silicon powder with the hydrogen chloride gas while the metallurgical grade silicon powder is fluidized by the hydrogen chloride gas and the metallurgical grade silicon powder and hydrogen chloride gas flow upward between the gas flow controlling members; and a step of discharging a reacted fluid containing trichlorosilane and the metallurgical grade silicon from a top part of the reactor into the gas discharge device.
