Blue tungsten oxide nanopowder for transparent thermal insulation film is mostly produced by adopting static reduction method in the current industrial production as the relationship between the process parameters and the particle size of tungsten powder is quite clear. As you may have known, the static reduction is one of the ways divided according to the flow pattern of materials, and the other way is dynamic reduction. Certainly, the dynamic reduction of rotary reduction furnace is also generally valued as…

Blue tungsten oxide nano powder may be used not only for the preparation of transparent thermal insulation film, which is widely used in the heat insulation fields of architectural window glass and automobile window glass, and can also be used in the preparation of tungsten powder by hydrogen reduction method. Some scholars have studied the relationship between the process parameters of blue tungsten oxide reduction process and the particle size of tungsten powder in industrial rotary reduction furnace, and analyzed…

Nano grain size blue tungsten oxide for transparent thermal insulation film is the most widely used raw material in the production of tungsten carbide powder. And blue tungsten oxide powder is usually prepared by weak hydrogen reduction using ammonium paratungstate (APT) as a raw material. The blue tungsten oxide powder obtained maintains the pseudomorphic morphology of the raw material APT. The main phase components of blue tungsten oxide are WO3 and WO2.90, and some blue tungsten oxide powders also have…
