Abstract

Hexachlorodisilane is decomposed into hydrochloric acid, silicon dioxide and water by introducing hexachlorodisilane-containing flue gas into a reaction region without moistening the flue gas and by supplying oxygen-containing gas that also contains a small amount of moisture to the reaction region maintained at a temperature at which hexachlorodisilane decomposes.
