Abstract
Alkali-metal-titanium fluorides are prepared by reacting titanium tetrachloride as a frozen solid with an aqueous solution of alkali metal fluoride. The reaction product, alkali metal titanium fluoride and alkali metal chloride, may, after dehydration, be used as such as an electrolyte in the electrolytic production of metallic titanium, in which case the amount of alkali metal chloride in the product may be adjusted by effecting the reaction in the presence of alkali metal chloride which need not be the same as that produced in the reaction; alternatively the alkali metal titanium fluoride may be separated from the alkali metal chloride formed. The amount of titanium tetrachloride supplied at any time should not be more than the stoichiometric amount in relation to alkali metal fluoride present. It is preferred to supply the titanium tetrachloride into the solution from one or more points below the surface thereof. The amount of water employed for the solution of the alkali metal fluoride should be kept at a minimum in order that the alkali metal titanium fluoride may be crystallized out, if desired, at the termination of the reaction. According to examples: (I) potassium fluoride was dissolved in water, the solution cooled to about 10 DEG C. and a frozen block of titanium tetrachloride at - 30 DEG C. placed in the bottom of the reactor and held below the surface of the solution. A slurry of potassium titanium fluoride and potassium chloride was obtained and the precipitated pure potassium titanium fluoride was removed from the salt solution. (II) A mixed salt containing potassium titanium fluoride and potassium chloride was obtained as in (I) above except that the aqueous solution initially contained potassium chloride and that the reaction slurry was evaporated to dryness at 115-120 DEG C. to produce a solid crystalline mixture of potassium titanium fluoride and potassium chloride in a weight ratio of 1 to 2.35. A further example relates to sodium titanium fluoride production.
