REACTIONS OF FLUORIDE ION WITH HYDROXYAPATITE

REACTIONS OF FLUORIDE ION WITH HYDROXYAPATITE teeth as well as bones consists chiefly of a basic calcium phosphate which is most probably hydroxyapatite (2, 3). Hydroxyapatites may be syn- formation of calcium fluoride, and very little or no fluorapatite.

As calcium fluoride, it occurs as fluorite, or fluorspar. It will also absorb water, converting itself into calcium hydroxide and releasing heat in the process. The bubbling that accompanies the reaction is the source of its name as "quick," or living, lime. The reaction of quicklime with water is sometimes used in portable heat sources.
