What is SiF4? Important knowledge about SiF4.

  1. Definition of SiF4
    SiF4, also known as Tetrafluorosilane or Silicon tetrafluoride in English, is an inorganic chemical compound. This molecule consists of a silicon atom linked to four fluorine atoms. The atomic mass of silicon is 28.0855 while the atomic mass of fluorine is 18.9984. The total atomic mass of the SiF4 molecule is 104.0795 amu. The SiF4 molecule does not form ions, but acts as a non-ionic substance in chemical reactions.

  2. Properties of SiF4
    The physical properties of SiF4 include: it is a colorless liquid at room temperature, has no specific smell, and its pH cannot be measured because it does not contain hydro or hydroxide ions. The chemical properties of SiF4 include its ability to react with water to form silicon dioxide and hydrogen fluoride.

  3. Common chemical reactions of SiF4
    SiF4 does not react with metals, acids, or salts. However, it can react with other nonmetals such as hydrogen to form hydrogen fluoride and silicon. For example: SiF4 + 2H2 -> 4HF + Si

  4. Synthesis of SiF4
    The synthesis of SiF4 in the laboratory usually involves the reaction of silicon with fluorine to form SiF4. Industrially, SiF4 is commonly produced from the reaction between silicon dioxide and hydrogen fluoride as follows: SiO2 + 4HF -> SiF4 + 2H2O.
