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