Abstract
A structure for mounting a novel reaction tube is capable of following up the thermal expansion of the reaction tube without the need of hanging down the reaction tube in the apparatus for producing silicon. In a reaction unit in a reaction vessel body of the apparatus for producing silicon, there are provided a gas feed pipe for feeding chlorosilanes and hydrogen, a reaction tube for precipitating silicon, a high-frequency coil arranged on the outer circumferential side of the reaction tube to melt the precipitated silicon, a heat insulating material provided between the reaction tube and the high-frequency coil, and an intermediate wall provided at the lower portion of the reaction unit to support the heat insulating material. The reaction tube is supported on the upper surface of the intermediate wall.
