The physical and technological features of the GC technology for producing secondary high-purity fine powders of copper, palladium as the starting materials of catalysts for microwave EVP and small-sized sealed CO2-lasers are presented.
It is shown that the microdispersed powders of copper, palladium and intermetallic compounds of palladium with barium (Pd5Ba) fully meet the requirements for the initial materials for the manufacture of vacuum and gas-discharge equipment.
Technical methods of producing cylindrical products and composite tapes by pressing, sintering and rolling are described. The features of the surface of palladium-barium composite tapes and their products immediately after the process of their manufacture are studied. Composite materials from fine secondary powders of copper and palladium are not inferior in their main physical parameters to the known ones, and they are superior in technical and economic efficiency.
