Abstract

Nano-sized WS2 based powders were synthesized by chemical vapor condensation (CVC) process using tungsten carbonyl (W(CO)6) as precursor and vaporized sulphur. Prior to WS2 nanopowders synthesis, pure tungsten nanopowders were produced by chemical vapor condensation to define the optimum synthesis parameters, which were then successfully applied to synthesize tungsten disulphide. The influence of experimental parameters on phase and chemical composition as well as mean size of the particles in order to produce pure tungsten and WS2 nanopowders was studied. Structure, phase composition and particles size of WS2 nanoparticles were precisely characterized by means of XRD, FESEM and TEM.
