Abstract
By employing an open-air plasma dynamic synthesis technique in a coaxial magnetoplasma accelerator, ultrafine copper oxide powders are produced. Using the methods of SEM, TEM, XRD structural analysis, and IR spectroscopy, it is shown that annealing in air at temperatures up to 800°C results in changes in the phase composition of the powder, as well as in the formation of a nanodispersed product whose main crystalline phase is copper oxide CuO.
