| Zusammenfassung: | The invention relates to the field of organic silicon, in particular to a method which uses the waste contacts generated in organic chlorosilane for preparing trichlorosilane. The invention is characterized in that the waste contacts is used as a raw material and then synthesized with dry HCl which is diluted by diluent gas by gas-solid phase direct method for preparing trichlorosilane. The prepared trichlorosilane can be used for the synthesis of single crystal silicon, polycrystalline silicon, high purity silicon and special type organic silane and the like. |
