Incredibly higher purity silicon for semiconductors is acquired using the Siemens course of action; the silicon is reacted to provide trichlorosilane, which 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. https://gunnerkmkhh.blogofchange.com/37259381/top-latest-five-silicon-carbide-semiconductor-urban-news
