Tetrachlorosilane is generated in the production process for polycrystalline silicon. Tokuyama purifies this material through distillation to produce high purity tetrachlorosilane.
・Raw material for synthetic quartz glass, optical fiber and synthetic quartz. Synthetic quartz glass is highly pure, transparent, heat resistant, and includes little metal impurities. For those characteristics, synthetic quartz glass is utilized for optical fiber,photomask, and other applications.
・Raw material for fumed silica, the company's product "REOLOSIL".
・Tetrachlorosilane is a colorless liquid at nomal temperature.There is a pungent odor.
・It reacts violently with water,strong oxidants,strong acids, alcohol, alkali,ketones and aldehyde, then produces hydrogen chloride.
