THE PRODUCTION OF FLUOROTITANATES

摘要

A process for the production of a substantially pure salt of fluorotitanic acid from an impure titanium source comprising dissolving the titanium source in hydrofluoric acid, treating the thus formed solution with an ammonium or alkali metal halide or nitrate in sufficient quantity to precipitate ammonium or alkali metal fluorotitanate and recovering the said fluorotitanate, wherein a mineral or synthetic rutile is used as the titanium source and the said source is dissolved directly in concentrated hydrofluoric acid.
