General description

Silicon tetrachloride (SiCl4) is an inorganic compound. It′s crystal structure is similar to that of carbon tetrachloride (CCl4). SiCl4 can be synthesized by the chlorination of silicon compounds (e.g. Mg2Si, SiC, SiO2/C).

Application

SiCl4 may be used;
  • in the preparation of high purity silicon, high purity silicon derived from silicon tetrachloride may find major applications in the semiconductors industry and in photovoltaic cells.
  • to dealuminate zeolite, mordenite.
  • as a coupling agent for the synthesis of amine from carboxylic acid and an amide.
  • in the synthesis of nanosilica.
