“…XRD results showed presence tungsten oxide film on nanoparticles surface, which is typical for tungsten nanopowders [7,8]. Interaction of metal and sulfur powders is self-propagating synthesis which is characterized by high temperature (1600-2000 °C [14]) and described by 2 nd type elementary combustion model [13]. In this model combustion of reagents is specified by low-melt reagent (sulfur) properties.…”

“…Relative density is ratio of practical density of pressed reaction mixture to maximum theoretical one. Low relative density resulted in higher boiling sulphur loss from reaction area, interaction of samples with density more than 0.8 was initiated difficulty [13]. Height of stoichiometric tungsten and molybdenum with sulphur mixture samples of diameter 32 mm was 14 and 23 mm, respectively.…”

Efficient two-step technique of tungsten and molybdenum disulfides obtaining from metal nanopowders produced by EEW and elementary sulphur is described. Tungsten and molybdenum nanopowders surface area dependence on wire length is studied. Features of metal and sulphur combustion process are discussed. It is determined sulphur excess in reagents 15 wt.% results in mono-phase metal disulfide formation with small free sulphur concentration in reaction products.
