Abstract:
It is shown that the use of hydrocarbonyl method of obtaining powders with a particle size of 0,5−10 microns is at present a challenge. It is described that the resulting fine Pd powder has a wide range of applications in powder metallurgy. We studied in detail the physical properties of fine palladium powder and studied the production of composite nanostructures particular a palladium powder and particles made of an intermetallic compound of palladium by barium alloy melt in a quartz ampoule, followed by grinding to a powder. Made from this mixture of powders composite tape Pd + Pd5Ba by powder metallurgy techniques can serve as effective electron sources in modern devices. In studies, performed modern analytical instruments and a high-resolution instrument were applied.
