The article discusses the investigations into the phase and chemical composition of nanopowders produced upon electrical explosion of conductors made of tin-lead alloy (POS-61) in air. It is demonstrated that, in the course of electrical explosion and subsequent cooling of the dispersion products, there occurs a slight enrichment (by 3-6 at %) of the surface and subsurface layers of the powder particles with lead in comparison with its content in the initial alloy.
