Abstract

Comparative analysis of factors shape and particle size of the powders of alloys of Cu—S and Cu—P, obtained using the original copper powder brand ПМС-1. The factors roundness, compactness, odourant, notched and the average diameter of the sphere of pure copper powders and alloys was identified. It is shown that through the use of original powder with high formability, middle temperature furnace synthesis and low-energy methods of grinding products synthesis even at partial melting and change the shape of the particles was able to obtain powders of alloys of Cu—S and Cu—P, have high formability. In the process of synthesis and subsequent pulverization of the synthesized product was partial destruction of the dendritic structure of the source powder, as evidenced by the reduction in the average diameter of the sphere (Cu — 44,8 μm, Cu—S — 9,5 µm, Cu—P — 12,2 μm).
