Potassium hexafluorozirconate is an inorganic compoundofpotassium, fluorine, and zirconium with the chemical formula K2ZrF6.[1][2]
Potassium hexafluorozirconate can be prepared from precipitation from solutions:
Also, in industry, it is obtained by sintering zirconium ore concentrates with K2SiF6 at 600–700 °C.[3]
Potassium hexafluorozirconate forms an odorless white crystalline powder.
It crystallizes in the monoclinic space group C 2/c (space group No. 15).[4]
Potassium hexafluorozirconate is used as an intermediate product in the electrolytic production of metallic zirconium.
It is also used as a flame retardant for wool,[5] grain refining agent in magnesium and aluminum alloys, welding flux, and optical glass component.[6]
