It is understood that trichlorosilane is also called trichlorosilane, which is a colorless, transparent liquid with irritating, odor, and easy to flow and volatile under normal temperature and pressure. It is extremely flammable in the air and has a fire risk below -18°C. It burns intensely in the event of a fire, and emits a red flame and white smoke when it burns. Trichlorosilane reacts with water to produce hydrogen chloride, hydrogen, and silicon dioxide, and emits a lot of heat, which can cause equipment corrosion and potential safety hazards. If it encounters water in the open air, it can cause burning and burning. The burning vapor can form explosive mixtures with air in a wide range of concentrations and cause violent explosion when heated.
