A series of synthetic carbonated and non-carbonated apatites was investigated using high resolution transmission electron microscopy, and their dissolution behavior was tested under sink conditions, using the rotating disc method. n-Beam lattice images of the apatite samples were of a resolution greater than has been previously reported, and revealed an increase in crystalline disorder with the incorporation of carbonate in the apatite structure. This resulted in an increased rate of dissolution and a decreased activation energy for dissolution for the carbonated apatites. Thus, carbonate increased the reactivity of hydroxyapatite.
使用高分辨率透射电子显微镜对一系列合成的碳酸化和非碳酸化磷灰石进行了研究，并采用旋转圆盘法在汇流条件下测试了它们的溶解行为。磷灰石样品的n束晶格图像分辨率高于先前报道的分辨率，并且显示随着碳酸盐掺入磷灰石结构中，晶体无序度增加。这导致碳酸化磷灰石的溶解速率增加，溶解活化能降低。因此，碳酸盐提高了羟基磷灰石的反应活性。
