In present work we observed structural phase state formation of Ag-Cu nanoparticles by electrical explosive of wires. We observed the formation of bimetallic nanoparticles with a number average size of 75 ... 82 nm by synchronous and nonsynchronous electric explosion of wires. The phase composition of the samples is represented by phases based on solid solutions of copper and silver. The results of the studies allow us to conclude that, using electric explosion of copper and silver wires, bimetallic Ag-Cu nanoparticles with different mass ratio of metals can be obtained.

Electrical Explosion Of Wires

Copper and molybdenum sulfide nanopowders were prepared by self-propagating high-temperature synthesis in argon. The initial copper powder and molybdenum powder were produced by electric spark dispersion in hexane and by electrical explosion of wires (EEW) in argon, respectively. The powders were studied by electron microscopy, X-ray diffraction and Raman spectroscopy. The copper sulfide main phase is hexagonal 2H-CuS, whereas hexagonal 2H-MoS2 and rhombohedral 3R-MoS2 are characteristic for molybdenum disulfide. The lattice parameters of copper and molybdenum sulfides were calculated. The average particle size of copper sulfide and molybdenum disulfide powders was about 50 nm and 80 nm, respectively.
