The paper presents experimental data on the dynamic registration of the sizes of condensed carbon nanoparticles upon detonation of oxygen-deficient energetic materials (EMs). The nanoparticle sizes were restored after processing of the measured distributions of small-angle X-ray scattering (SAXS). The work was carried out on the VEPP 3-4 accelerator complex (BINP SB RAS). The dynamically measured dimensions of carbon nanoparticles are ~ 2–4 nm near the chemical reaction zone (CRZ). The size of carbon nanoparticles is maximum beyond the chemical reaction zone and is ~ 5-8 nm in TNT/RDX mixtures, and ~ 70 nm in BTF. With increase in the charge diameters from 20 mm to 40 mm (and the charge mass from 20 g to 200 g), the sizes of condensed nanoparticles grow by 15–20%.
