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.
研究了氟离子掺入羟基磷灰石（HAp）/明胶（GEL）纳米复合材料的情况。氟离子掺入HAp相的OH(-)位点是一个能量活跃的过程，这可以从喷雾溶液反应中得到证实。通过空气喷雾将水中的Ca(2+)前体和明胶水溶液中的磷酸盐在加湿空气室中混合，然后将沉淀物在反应器中陈化。氟离子前体溶解在水中Ca(OH)(2)的起始溶液中，生成的Ca(OH,F)(2)复合液滴诱导形成稳定的氟磷灰石（F,OH）Ap。通过透射电子显微镜（TEM）形态、能量色散谱（ED）、X射线衍射（XRD）和傅里叶变换红外光谱（FT-IR）分析可以推测反应动力学。
