Annealing and investigation of copper oxide synthesized using coaxial magnetoplasma accelerator

Abstract

The synthesis of copper oxides has a great importance due to the fact these materials are widely used in high temperature superconductors manufacturing. It's known that properties of materials in nanodispersed conditions are improved. In this article, an analysis of nanodispersed plasma dynamic synthesis product obtained using coaxial magnetoplasma accelerator with copper electrodes was carried out. The obtained powder was analyzed by X-ray diffractometer Shimadzu XRD 7000 using the temperature consoles. Using this analysis such phases as Cu, Cu2O, CuO, Cu(OH)2·H2O were identified in the product. By gradually heating, the powder to the temperature of 800 °C the phase change was observed. The mass of copper oxide increased up to 96% and copper hydroxide hydrate.
