Abstract

The present invention relates to a high purity synthetic fluorite (caf2). Moreover, the present invention relates to a process for the preparation of said high purity synthetic fluorite (caf2), classified as acid grade, starting from fluorosilicic acid h2s1f6 (fsa) and calcium carbonate (caco3). Finally, the present invention relates to the use of said high purity synthetic fluorite (caf2) in the industrial production of hydrofluoric acid.
