Abstract:
Embodiments of a method for reducing iron silicide and/or iron phosphide fouling and/or corrosion in a hydrochlorosilane production plant are disclosed. Sufficient trichlorosilane is included in a silicon tetrachloride process stream to minimize hydrogen chloride formation, thereby inhibiting iron (II) chloride formation and reducing iron silicide and/or iron phosphide fouling, superheater corrosion, or a combination thereof.
