Potassium hexafluorotitanate is an inorganic compound of potassium, fluorine, and titanium with the chemical formula K2TiF6.[2][3]

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.[4] Potassium hexafluorotitanate is soluble in hot water, slightly soluble in cold water, and inorganic acid. Insoluble in ammonia.[5]

Chemical properties

Reacts with sodium to form titanium, potassium monofluoride and sodium monofluoride:[6][7]

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.[8]
