Quite superior purity silicon for semiconductors is attained utilizing the Siemens process; the silicon is reacted to provide trichlorosilane, which can be 1st purified by distillation, then reacted with purified hydrogen on significant purity silicon rods at 1150 oC to produce significant purity, polycrystalline silicon with hydrochloric acid byproduct.
