When it comes to the downstream development and utilization of polycrystalline silicon by-products, what people used to think of first was undoubtedly the development and utilization of silicon tetrachloride, which can be used to produce materials like fumed silica. However, the polysilicon industry is currently in a downturn; most companies have launched hydrogenation projects and no longer sell silicon tetrachloride, instead converting it into trichlorosilane for their own use. Now, one can consider the application of hydrogen chloride; it can be absorbed to form hydrochloric acid for external use, and the steam condensate can also be utilized.
