Potassium hexafluorotitanate

Potassium hexafluorotitanate is an inorganic compound of potassium, fluorine, and titanium with the chemical formula K2TiF6.

Synthesis
Hydrofluoric acid reacts with metatitanic acid to generate fluorotitanic acid; then it is neutralized with potassium hydroxide to produce potassium hexafluorotitanate.

Physical properties
The compound forms white powder. Potassium hexafluorotitanate is soluble in hot water, slightly soluble in cold water, and inorganic acid. Insoluble in ammonia.

Chemical properties
Reacts with sodium to form titanium, potassium monofluoride and sodium monofluoride:
 * K2TiF6 + 4Na -> Ti + 2KF + 4NaF

Uses
The compound is used as an analytical reagent, also used in the manufacture of titanic acid and metallic titanium. Can also be used as a catalyst for polypropylene synthesis. It is a component of the metal phosphating surface adjustment.
