Ca binds with F forming calcium-fluoride, which is insoluble in the gastrointestinal tract, preventing absorption (measured as a fall in urinary F) and therefore reducing the extent of F exposure. In this way it is postulated that the adverse effects of F are decreased and/or do not worsen with Ca intake.

Calcium fluoride, scaling - Big Chemical Encyclopedia

Calcium fluoride, solubility - Big Chemical Encyclopedia

Like most salts, calcium fluoride is an ionic compound that dissociates into ions when it dissolves in water. Calcium fluoride is also one of a large class of salts that are said to be slightly soluble in water. The ions in solution and any solid salt are at equilibrium, as the following equation for CaF2 and water shows. [Pg.525]

Calcium fluoride, scaling - Big Chemical Encyclopedia

Calcium fluoride scale can form when the concentration of fluoride is as low as 0.1 ppm if the concentration of calcium is high. Scaling will occur when the ion product exceeds the solubility constant. Antisealants or sodium softening can be used to control calcium fluoride scale. [Pg.138] Antisealants are usually fed alone for most applications.

Calcium Fluoride - an overview | ScienceDirect Topics

Calcium fluoride (CaF2) exists in nature as the mineral fluorite. Fluorite exhibits a strong radiation-induced TL and, after special treatment, can be used satisfactorily for radiation dosimetry purposes. The first reported use of the "radiothermoluminescence" of natural calcium fluoride occurred in 1903.
