1. a Fluoride salt production method, it is characterized in that:

  • in the crucible in electric furnace, have the fluoride of molten condition, electric furnace is persistently energized and heats crucible, raw material is injected in crucible by feed arrangement, carries out adding heat fusing, be divided into three parts after the raw materials melt reaction in crucible;

    top layer is carbon dust, middle level is fluoride, bottom is the metal impurities of precipitation, is proposed by the fluoride in middle level by drawing mechanism after having reacted, and puts in mould and obtains fluoride salt product after cooling;

    Again add raw material, repeat above procedure;
