Full Answer

Silicon tetrachloride is a liquid at room temperature and normal atmospheric pressure, but volatile enough to produce fumes. It is not soluble in water and reacts to form silicon dioxide and hydrochloric acid when mixed with water. Silicon tetrachloride is soluble in benzene, chloroform, ether and hydrochloric acid. It is most commonly used to purify elemental silicon used in microchips and other computer applications.
