| Abstract: | Nowadays,internal by-product silicon tetrafluoride in wet-process phosphoric acid production are utilized mainly to make fluosilicic acid by water absorption,further to sodium fluorosilicate,besides,the small amount of such by product is used to make aluminium fluoride,hydrofluoric acid and cryolite.Current status for preparation technique of cryolite from byproduct at home and abroad was reviewed,and the advantage and disadvantage of the process were also analyzed.The new approach to comprehensive utilizat... |
