Beschreibung

Allgemeine Beschreibung

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).

Anwendung

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.
