Silicon tetrachloride is a colourless liquid with a characteristic, sharp odour. In water it is broken down into hydrochloric acid with a release of heat. In the presence of moisture, the product is corrosive to metals and tissues. The declared product purity of 99.9999% enables the production of high-quality glass fibres, which contributes to more effective signal processing and faster data transfer in optical fibres.
The product is also of major importance to the electronics industry as a raw material for the production of ultra-pure polysilicon intended for silicon wafer manufacturing.
Purified silicon tetrachloride serves as a precursor for depositing the first crystalline silicon layer in the semi-conductor production process. Thanks to its properties, the product is one of the most important materials in the photovoltaic industry.
Ultra-pure silicon tetrachloride is also a material used in the production of silicon used for manufacturing silicon anodes for lithium-ion batteries.
It is miscible with toluene, benzene, chloroform, carbon tetrachloride, petroleum ether, ether and hydrochloric acid. At a standard temperature and pressure, the product has the form of a transparent liquid. It reacts violently with water and additionally is corrosive and toxic. It does not spontaneously ignite at temperatures below 650°C, is not explosive and does not oxidise.
