Preparation of Hexachlorodisilane : Condensing the exhaust gas from the furnace for producing polysilicon by chlorosilane and hydrogen in order to separate out the hydrogen. The condensate will be distillated to separate out the unreacted chlorosilane and silicon tetrachloride (by-product), and then we distill it to recycle the hexachlorodisilane . Tetrachlorodisilane can be also recycled at the same time. The purity of the recycled hexachlorodisilane and tetrachlorodisilane will be much high than the production made of the silicon metal.

When you are using this chemical, please be cautious about it as the following:
The Hexachlorodisilane reacts violently with water and causes burns. Wear suitable protective clothing, gloves and eye/face protection before use it. If contact with eyes, rinse immediately with plenty of water and seek medical advice. If you feel unwell, seek medical advice immediately. When heated to decomposition or on contact with water, it emits toxic fumes of HCl and Cl^-. It should be stored at temperature of below 5° C.
