Calcium fluoride precipitation is important in many industrial fields such as electronics, laser and glass manufacture, and spectroscopy. The crystallization and dissolution reactions involving calcium fluoride are of concern in waste water treatment since fluoride is introduced into environment as a natural impurity in ores used to produce phosphoric acid. In oral care application, calcium fluoride plays an important role in the topical application of fluoride solution to tooth enamel. Such treatment results in the partial transformation of hydroxyapatite to fluorapatite on the enamel surface resulting in a much caries resistant phase.In the present study biopolymers such as carboxymethyl inulin of varying degree of carboxylation and lignosulfonates have been tested as calcium fluoride inhibitors. Additionally, effect of biopolymers on calcium fluoride crystal morphology will be presented.
