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.
