Zirconium difluoride is an inorganic chemical compound with the chemical formula ZrF2.[1][2]
Synthesis
[edit]Zirconium difluoride can be prepared by the action of atomic hydrogen on thin layers of zirconium tetrafluoride, at a temperature of approximately 350°C.[3][4]
Physical properties
[edit]ZrF2 forms black crystals of the orthorhombic 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 form zirconium dioxide.[3]
Chemical properties
[edit]ZrF2 disproportionates when heated to 800 °C:[3]
- 2ZrF2 → ZrF4 + Zr
