METHOD FOR PRODUCING FLUORINATED POLYSILANES

摘要

The invention relates to a method for producing fluorinated polysilanes. Hydrogen fluoride and/or hexafluorosilicic acid, which are obtained in particular during acid digestion of mineral phosphates in the production of phosphate fertilisers, are used for the production of SiF4. The SiF4 obtained is thermally or plasma-chemically converted to fluorinated polysilane. The method is particularly efficient and cost-effective.
