Incredibly substantial purity silicon for semiconductors is acquired using the Siemens approach; the silicon is reacted to make trichlorosilane, which happens to be first purified by distillation, then reacted with purified hydrogen on high purity silicon rods at 1150 oC to yield high purity, polycrystalline silicon with hydrochloric acid byproduct. https://estrella-glass-lined-pipe92592.qodsblog.com/36632802/helping-the-others-realize-the-advantages-of-melting-point-of-titanium-carbide
