Applications

Dihydrogen hexafluorozirconate is used in manufacturing of optical glass and fluozirconate. It acts as a precursor to zirconium dioxide ceramic thin films. Further, it is used for surface pretreatments on steel to prevent corrosion. In addition to this, it is used in the production of the atomic energy industry, advanced electrical materials and refractories.

Notes

Incompatible with acids, strong oxidizing agents and bases.
