About Sodium monofluorophosphate - Tom's of Maine

Fluoride can be found in both fresh and sea water, in food (e.g., fish, tea), and in the bones of our bodies. In nature, it is found only in compound forms, such as the ore fluorspar (calcium fluoride) in soil and rock. To form sodium monofluorophosphate, sodium metaphosphate is combined with sodium fluoride.

Fluorine | chemical element | Britannica.com

Fluorspar is the most important source of fluorine. In the manufacture of hydrogen fluoride (HF), powdered fluorspar is distilled with concentrated sulfuric acid in a lead or cast-iron apparatus. During the distillation calcium sulfate (CaSO 4) is formed, which is insoluble in HF.

Calcium Fluoride - an overview | ScienceDirect Topics

Basic electrodes contain calcium fluoride (fluorspar – CaF 2) in the coating. The slag reacts as a base, thus leaving low sulphur and oxygen contents in the weld metal. The strength and toughness of the weld are therefore the strongest welds produced by any type of electrode, and the resistance to hot cracking is also higher.
