Abstract: | The structure of spherical hollow detonation nanodiamonds (DND) previously ground in a planetary mill for 10 min has been studied by synchrotron radiation diffraction. The interference contribution of the diffraction pattern from DND calculated using different structural parameters has been compared with the experimental pattern of DND after mechanical treatment. It was shown that after mechanical treatment of spherical hollow DND (rinner=19.94 A, router=25.47 A), two kinds of particles were observed: one was non-hollow spheres of r=13.9 A size at the same lattice parameters a=b=3.85 A, c=3.45 A and the others, of the size 5a×13b×5c at the parameters a=c=3.567 A, b=3.85 A, were particles of non-spherical shape. |
