Trichlorosilane (Cl₃HSi), molecular formula Cl₃HSi, is a colorless liquid with a pungent fishy smell, flammable and decomposes in water. Its low melting point (-134℃) and boiling point (31.8℃) characteristics make it:

Core of polysilicon production: Through the Siemens method or fluidized bed process, trichlorosilane can be distilled and purified to prepare electronic-grade polysilicon, providing key raw materials for chip manufacturing;
Starting point of the silicone industry chain: As a basic material for synthesizing silicone monomers (such as siloxane), it supports the production of downstream silicone oils, silicone resins and special rubbers;
Cross-border application of new energy: In the photovoltaic field, it cooperates with silicon tetrachloride to achieve efficient resource utilization through a closed-loop process and reduce production costs.
