The CAS registry number of Zinc fluoride is 7783-49-5. The IUPAC name is difluorozinc. Its EINECS registry number is 232-001-9. In addition, the molecular formula is F₂Zn and the molecular weight is 103.41. It is an inorganic chemical compound and belongs to the classes of Inorganics; Catalysis and Inorganic Chemistry; Chemical Synthesis; Salts; Zinc Salts; ZincMetal and Ceramic Science. And it has a high melting point and has the rutile structure containing 6 coordinate zinc, which suggests appreciable ionic character in its chemical bonding. What's more, it can be used as analysis reagent and impregnant of wood. It should be stored in sealed container, and put them in a cool and dry place.

Preparation of Zinc fluoride: Add carbonate zinc to excess hot hydrofluoric acid, it will form a clear solution at first. If continue to add the carbonate zinc, it will exhalate white opaque fluoride zinc crystal. And it can be prepared by zinc metal with fluorine gas. In addition, the reaction of hydrofluoric acid with zinc can yield hydrogen gas and zinc fluoride.

When you are using this chemical, please be cautious about it as the following:
It is toxic by inhalation, in contact with skin and if swallowed and irritating to eyes, respiratory system and skin. And it has risk of serious damage to eyes. During using it, wear suitable protective clothing, gloves and eye/face protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If it contact with skin, wash immediately with plenty of soap-suds. In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).
