  • Abstract
    The production of polycrystalline silicon (polysilicon) requires several main feedstocks. Polysilicon is produced by the reaction of trichlorosilane, SiHCl3 (TCS) with hydrogen, H2. Trichlorosilane is produced in the TCS plant while hydrogen is produced in H2 plant. Hydrogen and oxygen can be produced from water using electricity through the process of electrolysis. The purification or rectification of the H2 gas is typically done by passing an impure H2 stream over a heated palladium (Pd) alloy. The purity of H2 is then tested using a laboratory-constructed hydrogen gas purity test method which has been found to be at 99.9%.
