Abstract:
1. A method for producing trichlorosilane by reacting metal silicon powder with hydrogen chloride gas, thereby generating trichlorosilane, the method comprising: stacking a plurality of plate-shaped holed pieces having through holes penetrating in the thickness direction and a plurality of ball members interposed between the plate-shaped holed pieces in a mixed state on the upper side of a partition plate partitioning the bottom part of an apparatus body into which the metal silicon powder is supplied; and ejecting the hydrogen chloride gas from an ejection port, which is opened on the upper face of the partition plate, while supplying the metal silicon powder into the apparatus body, wherein the ball members and the plate-shaped holed pieces are mixed so as to give a mixture ratio of W1/W2=0.5 to 5 where a weight of the ball members is expressed as W1 and a weight of the plate-shaped holed pieces is expressed as W2.
