Nano violet tungsten oxide powder may be applied for the manufacture of nano-ceramic dispersion solution, which may be applied to prepare heat insulating film. The violet tungsten oxide can also be reduced in a hydrogen atmosphere to obtain tungsten powder, and the tungsten powder and carbon are mixed, carbonizing to obtain tungsten carbide powder, and then the morphology change of the obtained tungsten carbide powder is studied by transmission electron microscopy and scanning electron microscopy, as shown in the following…
