Uses and applications
What the substance is used for, by industry and function
Since 1991, fluoridated salt has been on sale in household-size packages in Germany. Potassium or sodium fluoride is added to iodized salt until the fluoride concentration reaches 250 mg/kg.
Salt fluoridation is recognised world-wide as a proven and viable alternative means of consumer choice-related, community-based fluoridation where water fluoridation is either technically or politically impossible. ...Most salt consumed is contained within cooked food products, rather than sprinkled over prepared food at the table.../Fluoride salts/.
Used in preparing silver soldering fluxes. ... In organic synthesis as a catalyst for various reactions or to introduce fluorine into organic molecules. ... In France, potassium fluoride may be added to table salt to increase resistance to dental caries.
Unscheduled precursor to sarin.
Used in etching glass, as a preservative, as an insecticide, and in organic synthesis ...
Industrial uses: Cleaning agent, Intermediate, Other, Processing aids not otherwise specified.
Consumer uses: Semiconductor and photovoltaic agent.
Use classes: Cosmetics.
