四氯化硅 空气 化学式英语
    Silicon tetrachloride, also known as tetrachlorosilane, is a colorless, fuming liquid with the chemical formula SiCl4. It is a highly reactive compound that reacts violently with water to produce hydrochloric acid and silicon dioxide. Silicon tetrachloride is used in the production of semiconductors and other silicon-based materials.
    Physical and Chemical Properties.
    Silicon tetrachloride is a volatile liquid with a boiling point of 57.6 °C and a freezing point of -68.8 °C. It is a non-flammable liquid but can react violently with water to produce hydrochloric acid and silicon dioxide. Silicon tetrachloride is also a corrosive liquid that can cause skin and eye irritation.
    Production.
    Silicon tetrachloride is produced by the reaction of silicon dioxide (SiO2) with chlorine gas (Cl2) in the presence of a catalyst. The reaction is carried out at high temperatures in a fluidiz
ed bed reactor.
    Applications.
    Silicon tetrachloride is used in the production of semiconductors and other silicon-based materials. It is also used as a chlorinating agent in the production of other chemicals.
    Safety Considerations.
    Silicon tetrachloride is a hazardous chemical that can cause skin and eye irritation. It is also a corrosive liquid that can damage metal surfaces. Silicon tetrachloride should be handled with care and appropriate personal protective equipment should be worn when working with it.
    Environmental Considerations.
    Silicon tetrachloride is a volatile organic compound (VOC) that can contribute to air pollution. It can also react with water to produce hydrochloric acid, which is a corrosive and
reactive substancetoxic substance. Silicon tetrachloride should be disposed of properly in accordance with local regulations.
