Abstract:
Nanodispersed carbon was obtained via high-temperature combustion of acetylene–oxygen mixtures in a flow-through tubular chamber in cyclic detonation waves (“pulsed detonation”) at a constant propagation velocity (D det ≈ 2150 m s –1 ). It was found that the position of a plateau in the curve describing how the detonation velocity depends on the content of oxygen in the starting detonation mixture in the range 15–30% coincides with the range of descending branches of the dependences of the specific adsorption surface area and adsorption of dibutyl phthalate by aggregated particles. Various physicochemical methods of analysis (X-ray diffraction analysis, Raman spectroscopy, high-resolution transmission electron microscopy, etc.) were used to comparatively examine the properties of nanodispersed carbon and of the known industrially produced domestic and foreign brands of technical-grade carbon. The conditions were found in which detonation nanocarbon particles are obtained in a certain range of parameters of micro- and macrostructures with improved morphology and basic electrical properties. © 2018, Pleiades Publishing, Ltd.
