Really significant purity silicon for semiconductors is attained utilizing the Siemens procedure; the silicon is reacted to supply trichlorosilane, and that is initially purified by distillation, then reacted with purified hydrogen on higher purity silicon rods at 1150 oC to yield large purity, polycrystalline silicon with hydrochloric acid byproduct.
