摘要：

Diamond nanoparticles have significant prospects for technological applications, so their manufacture and subsequent disaggregation are a challenging task. In this paper, the porous structure of aggregates in detonation nanodiamond powders has been analyzed using small-angle neutron scattering. The influence of high pressure allowed the contributions to the small-angle scattering from micro- and nano-sized pores to be separated. The type of fractal clusters formed by nanopores was determined. The possibility of a partial mechanical disaggregation of nanodiamond particles at a pressure of 1.5 GPa is confirmed.
