Preparation of nanocrystalline Cu-xMgO mixture

Nanocrystalline dispersion systems on the Cu-base belong to the progressive materials that have particularly found their applications in the fields th at place demands, besides specific physical and chemical properties of copp er (electrical conductivity, thermal conductivity), on improved mechanical properties or on the resistance of mechanical properties against thermal de gradation. The process of the formation of the secondary phase in the prepa ration process, as well as its stability after reduction of the CuO-MgO sys tem to the Cu-MgO system are studied in the presented paper.
