Abstract

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.
