The structure of ultrathin sections of dense submicrocrystalline hydroxyapatite (HA) (Ca10(PO4)6(OH)2) ceramics has been studied by X-ray diffraction and high-resolution transmission electron microscopy (TEM). The results demonstrate that high-energy electron irradiation can lead to surface modification with thin CaO, α-Ca3(PO4)2, and HA nanoparticles. Two-level interference contrast and double Fourier transformation of TEM images have been shown to be effective tools for revealing and identifying nanoparticles, respectively.
