In this paper, an interesting approach for activating the solid-state sintering of tungsten powders was proposed. In this approach, WO3 nanowires were formed on tungsten particles by addition of sub-micron particles as required oxygen source in powder mixture. High oxygen content of sub-micron particles acts as required oxygen source in formation of WO3 nanowires. The microstructural studies exhibited that, reduction of WO3 nanowires in hydrogen atmosphere led to formation of tungsten nanoparticles during sintering which can activate solid state sintering of compact.
