Potassium hexafluorotitanate Usage And Synthesis

Chemical Properties

White leaflets. Soluble in hot water.

Uses

Titanic acid, titanium metal.

Uses

Potassium hexafluorotitanate is used as analytical reagent, alloying additive, flame retardant and flux agent for casting. It is also used in the manufacture of titanium acid and aluminum alloys containing titanium. It is also employed in metal surface treatment and finishing, detergent applications and dental impression molding. Further, it is used as a catalyst for polypropylene synthesis. In addition to this, it is used in the extraction-refining-processing of metals, electrical-electronics engineering, textile processing and in ceramics-glass industries.

Hazard

Toxic material.

Flammability and Explosibility

Non flammable

reaction suitability

reagent type: catalyst
core: titanium

Materials Uses

Potassium hexafluorotitanate (K2TiF6) is a wettability agent, commonly used in the fabrication of Aluminum Matrix Composites (AMCs). During the casting process, argon shield gas is applied throughout the process, and 1 wt% K2TiF6 wettability agent is added into alloy^[1].

Safety Profile

Poison by subcutaneous route. When heated to decomposition it emits toxic fumes of K2O and F-. See also FLUORIDES.
