Abstract
A method for the production of titanium trifluoride from a titanium-containing material, includes the steps of producing a fluoride solution of Ti(IV) from the titanium-containing material and reducing the Ti(IV) in the solution with a transition metal or an alloy of the transition metal. The transition metal is selected from manganese, iron, cobalt, nickel and zinc. An ammonium containing salt and either ammonia or ammonium fluoride are added to the resulting solution containing Ti(III) to produce a precipitate, and the precipitate is pyrolysed to produce titanium trifluoride.

A method for the production of titanium trifluoride from a titanium-containing material, the method
- producing a fluoride solution of Ti(IV) from the titanium-containing material,
- reducing the Ti(IV) in the solution with a transition metal or an alloy of the transition metal, in which the transition metal is selected from the group consisting of manganese, iron, cobalt, nickel and zinc to produce a solution containing Ti(III),
- adding an ammonium containing salt and either ammonia or ammonium fluoride or a mixture thereof to the solution containing Ti(III) to produce a precipitate, and
- pyrolising the precipitate to produce titanium trifluoride.
A complex salt comprising NH4TiF4.NH4OH.
