10026-04-7 - Preparation Method

ferrosilicon chloride method: first, Ferrosilicon is added into the chlorination furnace, and then heated to about 300 ° C. 5 m3/h chlorine gas was introduced into the reaction to produce silicon tetrachloride, and after condensation, crude silicon tetrachloride was obtained. Antimony powder (0.05% by weight based on the weight of silicon tetrachloride) was added to the crude silicon tetrachloride for distillation, and the mixture was refluxed for 30min, and then a fraction of 56 to 59 ° C. Was taken to obtain a commercial grade silicon tetrachloride product. High-purity silicon tetrachloride can be obtained by further rectification of technical grade silicon tetrachloride and reflux for a long time.
