通过改变反应条件和添加谷氨酸，可以将氟部分取代羟基磷灰石（FHAp）的形貌从多刺的球状、帚状、花状、蒲公英状、纳米纤维状精细地调整到超长的纳米带状。X射线衍射，高分辨率透射电子显微镜，能量色散X射线光谱等进行表征所得粉末和分析的生长过程。通过对实验条件的综合比较，发现FHAp晶体的生长过程基本上是一个双重分裂的分形生长过程。
Morphologies of hydroxyapatite with partial substitution of fluorine (FHAp) have been finely modulated from prickly spheres, whisk brooms, flowers, dandelions, and nanofibers to ultralong nanoribbons through altering the reaction conditions and adding glutamic acid. X-ray diffraction, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, and so forth were performed for characterizing the resultant powders and analyzing the growth process. Condition experiments were compared comprehensively and revealed that FHAp crystals with various morphologies were formed, generally, through a fractal growth process of double splitting.
