chemical properties clear colorless liquid
uses sicl 4 may be used as an intermediate in the manufacture of high purity silicon. high purity silicon derived from silicon tetrachloride may find major applications in the semiconductors industry and photovoltaic cells. high purity sicl 4 may be used to manufacture of optical fibers.
general description tetrachlorosilane is a colorless, fuming liquid with a pungent odor. tetrachlorosilane is decomposed by water to hydrochloric acid with evolution of heat. tetrachlorosilane is corrosive to metals and tissue in the presence of moisture. tetrachlorosilane is used in smoke screens, to make various silicon containing chemicals, and in chemical analysis.
reactivity profile chlorosilanes, such as tetrachlorosilane, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. they may also produce flammable gaseous h2. they can serve as chlorination agents. chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. tetrachlorosilane is incompatible with alkali metals and dimethyl sulfoxide.
health hazard inhalation causes severe irritation of upper respiratory tract resulting in coughing, choking, and a feeling of suffocation; continued inhalation may produce ulceration of the nose, throat, and larynx; if inhaled deeply, edema of the lungs may occur. contact of liquid with eyes causes severe irritation and painful burns; may cause permanent visual impairment. liquid may cause severe burns of skin. repeated skin contact with dilute solutions or exposure to concentrated vapors may cause dermatitis. ingestion causes severe internal injury with pain in the throat and stomach, intense thirst, difficulty in swallowing, nausea, vomiting, and diarrhea; in severe cases, collapse and unconsciousness may result.
fire hazard behavior in fire: contact with water in foam applied to adjacent fires will produce irritating fumes of hydrogen chloride.
