High Carbon Trichlorosilane

The dried silicon powder reacts with the dried hydrogen chloride gas at 340°C in a chlorination fluidized bed furnace, and the generated crude trichlorosilane is separated into silicon tetrachloride by a wet dust collector and a pipe bundle condenser distillation tower, and then condensed to obtain the finished product. The product can also be obtained by the reaction of ferrosilicon and HCl.
