Zinc fluoride (ZnF2) is an inorganic chemical compound.
Conditions/substances to avoid are: dust generation, potassium, acids, water and moisture.
[edit] Synthesis
Zinc Fluoride can be synthesized several ways.
1. Reaction of a Fluoride salt with Zinc Chloride, to yield Zinc Fluoride and a Chloride salt, in aqueous solution.
2. The heating of pure zinc metal in an environment of pure fluorine gas. The zinc fluoride vapor would then be cooled
3. Reaction of Hydrofluoric Acid (HF) with pure zinc, to yield Hydrogen gas (H2) and Zinc Fluoride (ZnF2).
Several other methods likely exist, but would involve more complex reactions and most likely more than one or two steps.
