Potassium hexafluorozirconate explained

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

Preparation

Potassium hexafluorozirconate can be prepared from precipitation from solutions:

Also, in industry, it is obtained by sintering zirconium ore concentrates with 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]
