High-purity synthetic fluorite, method and equipment for preparing the same |
| abstract |
The present invention relates to high-purity synthetic fluorite ( CaF2 ). The present invention also relates to a method and apparatus for preparing said high purity synthetic fluorspar (CaF 2 ) classified as acid grade starting from fluosilicic acid H 2 SiF 6 (FSA) and calcium carbonate (CaCO 3 ). Finally, the present invention relates to the application of the high-purity synthetic fluorite (CaF 2 ) in the industrial manufacture of hydrofluoric acid. |
