Description and Uses
Zinc fluoride (ZnF2) is an inorganic chemical compound. Zinc fluoride is used in the fluorination of organic compounds, in the manufacturing of phosphors for fluorescent lights, in preserving wood, in electroplating baths, in galvanizing steel, and in ceramic manufacturing for glazes and enamels. It is also used as a termite repellent, in pharmaceuticals (e.g. the inhibition of dentin demineralization and collagen degradation), as a flux for welding and soldering (e.g. aluminum).
Zinc Difluoride inhibits the erosion of enamel in vitro. It also functions as a fluorinating agent, Lewis acid catalyst and as an additive for catalytic transformations.
