Potassium Hexafluorotitanate(IV) (TCI P2923), with the formula K₂TiF₆, is an inorganic complex salt containing the hexafluorotitanate anion, in which titanium is in the +4 oxidation state. Laboratories use it as a soluble titanium precursor that is relatively easy to handle. It is used to synthesise titanium dioxide materials and other titanium compounds, to produce aluminium alloys, to form conversion coatings on metal surfaces, and in research on fluoride-based luminescent phosphors. It is a practical starting material for both inorganic synthesis and materials research.
Researchers choose this compound because it supplies titanium as a stable fluoride complex. That makes it easier to store and weigh than titanium precursors that react strongly with moisture, such as titanium tetrachloride or titanium alkoxides. In aqueous solution, temperature and pH can be used to control how the TiF₆²⁻ anion hydrolyses. This lets researchers adjust the size, crystal phase and morphology of the TiO₂ particles that form. The fluoride ions released during hydrolysis can also act as shape-directing agents in hydrothermal synthesis, which gives more control over crystal growth and the final structure of the material.
In Indonesia, K₂TiF₆ is useful to materials science, metallurgy and inorganic chemistry laboratories at universities and research institutions. Research groups working on photocatalysts, functional oxide materials, surface treatment of metals and luminescent compounds can use it as a reliable titanium source for repeatable experiments. Because it is a stable fluoride complex, it suits teaching laboratories and research facilities that need a titanium precursor they can weigh accurately and handle under routine laboratory conditions.
- Titanium dioxide synthesis: controlled hydrolysis of the TiF₆²⁻ anion lets researchers tune the particle size, crystal phase and morphology of the TiO₂ product.
- Hydrothermal crystal engineering: the fluoride ions released from the complex can act as shape-directing agents, which helps control crystal growth and the facets that form in hydrothermal syntheses.
- Aluminium alloy preparation: the compound supplies titanium in a stable fluoride form, so it suits metallurgical research on alloys and grain refinement in aluminium systems.
- Conversion coatings on metal surfaces: as a soluble hexafluorotitanate salt, it suits studies of titanium-based conversion coatings used in surface treatment and corrosion research.
- Fluoride-based luminescent phosphors: the hexafluorotitanate framework makes it a useful starting material for research into fluoride host lattices for luminescent phosphors.

Store Potassium Hexafluorotitanate(IV) in its original, tightly closed container in a cool, dry, well-ventilated area, away from moisture, strong acids and incompatible materials. Contact with strong acids may release hazardous fluoride species, so keep the two apart. Handle the compound in a fume hood or a well-ventilated area to avoid inhaling dust. Wear chemical-resistant gloves, safety glasses and a laboratory coat. Label containers clearly, and dispose of waste containing fluoride according to local regulations and your institution's procedures. Always read the Safety Data Sheet (SDS) before use.
