磷矿伴生硅资源制备单质硅的探讨

Research on Preparation of Pure Silicon from Associated Silicon Resource in Phosphorite

综述了国内外以四氟化硅、氟硅酸钠(钾)、无定SiO2为硅源制备单质硅的主要方法,并对以无定SiO2为硅源制备单质硅的工艺条件进行了研究与探索。

This paper summarizes the main method of the preparation of pure silicon from silicon tetrafluoride,sodium fluosilicate（potassium fluosilicate） and amorphous silicon dioxide as the silicon sources.Simultaneously preparation of the pure silicon from amorphous silicon dioxide as the silicon source is studied.
