Nano violet tungsten oxide powder may be applied for preparing nano-ceramic color master. And the obtained color master has the advantages of high heat insulation and high transparency so that it can be applied for the production of heat insulating film. Violet tungsten oxide can also be used as a raw material for preparing submicron tungsten powder. Submicron W powder may be prepared by cyclic reduction oxidation method using a relatively simple phase composition of violet tungsten oxide. Compared with…

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…

Nano violet tungsten oxide powder may be used for the production of thermal insulation dispersion, which may be applied in the fields of heat insulation in the form of a thin film, such as building heat insulation film and car heat insulation film. Violet tungsten oxide can be used to prepare tungsten powder and tungsten carbide powder. Among them, there are two reasons for the coarser grain size of tungsten carbide than tungsten powder: 1. These powders have different densities.…
