Really superior purity silicon for semiconductors is obtained using the Siemens approach; the silicon is reacted to generate trichlorosilane, which can be initially purified by distillation, then reacted with purified hydrogen on large purity silicon rods at 1150 oC to generate high purity, polycrystalline silicon with hydrochloric acid byproduct.
