磷化工副产氟资源的利用现状及展望

摘要

介绍了当前萤石氟资源的紧缺及磷化工副产氟资源的利用现状,阐述了国内外利用磷化工副产物氟硅酸制备具有较高附加值的氟化物产品(如氟化氢、氟化铝、冰晶石等)的技术路径及优缺点,对磷化工副产氟资源潜在的巨大价值和应用前景作了展望.%This paper briefly introduces the acute shortage of fluorite fluorine resource at present and the status quo of utilizing the Fluorine by-product in phosphorus chemical industry ,overviews the technical route of producing high value-added fluoride products(such as hydrogen fluor-ide ,aluminum fluoride ,cryolite ,etc)with byproduct fluosilicic acidin phosphorus chemical industry and its advantages and disadvantages ,and looks into the prospect of great potential value of byproduct fluorine in phosphorus chemical industry and its future application .
