  • Title: Fluoride incorporation in hydroxyapatite/gelatin nanocomposite.
    Author: Chang MC.
    Journal: J Mater Sci Mater Med; 2008 Aug; 19(8):2837-43. PubMed ID: 18330679.
    Abstract:
    The incorporation of fluoride ion into hydroxyapatite (HAp)/gelatin (GEL) nanocomposite was investigated. The F(-) ion incorporation into OH(- )site of HAp phase was an energetically active process, which could be confirmed from the spray solution reaction. The precursors of Ca(2+) in water and phosphates in aqueous gelatin were mixed in the humidified air chamber by air spray, and then the precipitates were aged in a reactor. The F(-) ion precursor was dissolved in the starting solution of Ca(OH)(2) in water, and the resulted Ca(OH, F)(2) complex droplets induced the formation of stable fluoroapatite (F, OH)Ap. The reaction kinetics could be assumed from TEM morphology with ED, XRD and FT-IR analysis.
