对从骨和矿化肌腱中分离出的碳酸盐磷灰石晶体以及在近似生理条件下合成的碳酸盐磷灰石晶体进行的透射电子显微镜研究表明，它们是薄的不规则形状的板。单个晶体的电子衍射图证实了大的发达晶面是(100)，并且生物晶体的最长尺寸与晶体c轴对齐。由于后者也与胶原纤维轴对齐，因此观察结果提供了有关组织组织本身的附加信息。生物晶体和合成晶体之间的显着相似性表明，晶体形成的生物环境可能不是控制其形状的主要因素。
A transmission electron microscope study of carbonate apatite crystals isolated from bone and mineralizing tendon, as well as those produced synthetically under approximated-physiological conditions, shows that they are thin irregular shaped plates. Electron diffraction patterns of individual crystals confirm that the large developed crystal face is (100), and that the longest dimensions of the biogenic crystals are aligned with the crystallographic c axes. As the latter are also aligned with collagen fibril axes, the observations provide additional information on the tissue organization itself. The marked similarity between the biologic and synthetic crystals suggests that the biological environment in which the crystals form may not be primarily responsible for controlling their shape.
