ABSTRACT:
This apparatus for producing trichlorosilane includes: a vessel having a gas inlet that introduces a feed gas into the vessel and a gas outlet that discharges a reaction product gas to the outside; a plurality of silicon core rods provided inside the vessel; and a heating mechanism that heats the silicon core rods, wherein a feed gas containing silicon tetrachloride and hydrogen is reacted to produce a reaction product gas containing trichlorosilane and hydrogen chloride. The silicon core rods may be disposed so as to stand upright on the bottom of the vessel, and the heating mechanism may have electrode portions that hold the lower end portions of the silicon core rods on the bottom of the vessel and a power supply that applies an electric current to the silicon core rods through the electrode portions to heat the silicon core rods.
