Results of investigation of the dispersed, phase, and chemical compositions of products of plasma dynamic synthesis in a high-speed pulsed jet of copper-containing electroerosive plasma flowing into a closed volume with the air atmosphere are presented. Products of synthesis are investigated by the methods of x-ray phase and thermal analyses, electron microscopy, and IR spectroscopy. The structure of the synthesized powder includes metal copper, Cu2О and CuO copper oxides, and hydrated copper hydroxide Cu(OH)2·Н2О. Results of investigations of structural changes of the synthesized products during heating in vacuum and air are presented.
