Why detonation nanodiamonds are small

Abstract

Based on X-ray diffraction patterns and an original atom distribution calculation by the proposed computer models, we infer that there exist high-quality and poor-quality detonation nanodiamonds. It has been demonstrated that the high-quality detonation nanodiamonds are small in size and have a structure corresponding to that of macrodiamond, while poor-quality ones consist of a core and a shell whose atom distribution has been disturbed and differs from that in macrodiamond.
