Potassium hexafluorozirconate is an inorganic compound of potassium, fluorine, and zirconium with the chemical formula K2ZrF6.[1][2]

Preparation

Potassium hexafluorozirconate can be prepared from precipitation from solutions:

2KF + ZrF4 → K2ZrF6↓
2KCl + (NH4)2ZrF6 → K2ZrF6↓ + 2NH4Cl

Also, in industry, it is obtained by sintering zirconium ore concentrates with K2SiF6 at 600–700 °C.[3]

Physical properties

Potassium hexafluorozirconate forms an odorless white crystalline powder.

It crystallizes in the monoclinic space group C 2/c (space group No. 15).[4]

Uses

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]
