An X-ray diffraction study of crystal structure of bone apatite of Mongols and its changes and dependence on human ages has been carried out. The FullProt program based on the Rietveld method was used. In apart from separating proteins molecule off each sample was heated at 800°C during 30 minutes. Not depending on this heat treatment of all the samples consist only the fluoric apatite (Ca5(PO4)F) phase. As a result of refinement of the diffractograms it was established variation of parameters of bone apatite crystal structures (the unite cell constants, the coordinates of atoms, Debye-Waller heat factors of atoms, the atom contents and the unite cell volume) on different ways. It is also evident that the Ca1 atomic content increases with aging. |
