Study of Tungsten and Molybdenum Nanopowders Interaction with Sulphur in SHS Conditions and Synthesized Product Properties

Abstract:

X-ray and transmission electron microscopy results of initial tungsten and molybdenum nanopowders produced by electrical explosion of wire and used in metal sulfides synthesis is presented. Sulphur excess effect on metal nanopowders combustion with elementary sulphur and phase composition of products is studied. Tungsten and molybdenum disulfides obtained by self-propagating high-temperature synthesis under argon pressure 3 MPa and sulphur excess 15 wt. % in initial mixture are crystallized in layered aggregates with layer thickness 20-30 nm.
