Carbon Condensation During Detonation of High Explosives of Various Diameters

This paper presents experimental data on monitoring of condensed carbon nanoparticles during the detonation of TNT/RDX charges 20, 30 and 40 mm in diameter. The dynamics of nanoparticles sizes were derived from processing of measured distributions of small-angle X-ray scattering (SAXS). SAXS is investigated via registering the diffraction signal from a sample in the small area. This method is widely used for analysis of the structure of disperse systems. The work was carried out at the accelerator complex VEPP-4M (BINP SB RAS). Nanoparticles of 4 nm size was detected behind the detonation front, after that the average size of particles increases up to 9 nm during 3–4 microsecond for all charges.
