Fluorapatite as a naturally occurring impurity in apatite generates hydrogen fluoride as a byproduct during the production of phosphoric acid, as apatite is digested by sulfuric acid. The hydrogen fluoride byproduct is now one of the industrial sources of hydrofluoric acid , which in turn is used as a starting reagent for synthesis of a range ...
Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca 10 ( PO 4 ) 6 (OH,F,Cl) 2 , and the crystal unit cell formulae of the ...
Sodium monofluorophosphate, commonly abbreviated SMFP, is an inorganic compound with the chemical formula Na 2 PO 3 F. Typical for a salt, SMFP is odourless, colourless, and water-soluble. This salt is an ingredient in some toothpastes .
Monofluorophosphate is an anion with the formula PO 3 F 2−, which is a phosphate group with one oxygen atom substituted with a fluoride atom.The charge of the ion is −2. The ion resembles sulfate in size, shape and charge, and can thus form compounds with the same structure as sulfate
Fluoride-containing compounds, such as sodium fluoride or sodium monofluorophosphate are used in topical and systemic fluoride therapy for preventing tooth decay. They are used for water fluoridation and in many products associated with oral hygiene . [ 31 ]
Fluoride can be delivered by many chemical methods (sodium fluoride, stannous fluoride, amine fluoride, monofluorophosphate, and more). The anti-caries performance differences between them have been shown to have less effect than variations in behavior shown by individuals in brushing, using fluoride products and post use behavior.
They are distinct from the fluorophosphates: monofluorophosphate, ... Iron-Doped Sodium–Vanadium Fluorophosphate Na 3 V 2–y O 2–y Fe y (PO 4) 2 F 1+y (y < 0.3)
