ABSTRACT:
A process for the preparation of metal fluorides usable for the production of fluoride glasses consists of reacting in an organic liquid medium, such as toluene, (a) a compound of said metal chosen from among the gaseous compounds thereof, the compounds of said metal soluble in the organic liquid medium and the compounds of said metal in solution in an organic solvent miscible with said medium, and (b) a fluorinating agent chosen from among the gaseous fluorinating agents, the fluorinating agents which are partly soluble in the organic medium and the fluorinating agents which are partly soluble in an organic solvent miscible with said medium, to form a fluoride of said metal, the organic liquid medium being such that it reacts neither with the compound of the metal, nor with the fluorinating agent and does not dissolve the fluoride formed. To prepare the zirconium tetrafluoride, it is possible to introduce in toluene, gaseous Zr(BH.sub.4).sub.4 entrained by argon from the container and HF vapor also entrained by the argon from the other container. ZrF.sub.4 precipitates in the toluene and is separated on the filter.
