Zirconium difluoride is an inorganicchemical compound with the chemical formulaZrF2.[1][2]
Zirconium difluoride can be prepared by the action of atomic hydrogen on thin layers ofzirconium tetrafluoride, at a temperature of approximately 350 °C.[3][4]
ZrF2 forms black crystals of theorthorhombic system, with unit cell parameters a = 0.409 nm, b = 0.491 nm, c = 0.656 nm.[3]
The compound readily ignites and burns to formzirconium dioxide.[3]
ZrF2 disproportionates when heated to 800 °C:[3]
