Extremely large purity silicon for semiconductors is received using the Siemens course of action; the silicon is reacted to generate trichlorosilane, that is 1st purified by distillation, then reacted with purified hydrogen on higher purity silicon rods at 1150 oC to yield high purity, polycrystalline silicon with hydrochloric acid byproduct. https://glasslinedcarbonsteelpipe18492.ourcodeblog.com/36814036/a-review-of-density-of-tic
