WO3 powder for producing WO3-TiO2 electrochromic film has the advantages of large color range and high coloring efficiency, and therefore, it has received more extensive attention than other electrochromic materials. Experts said that smart glass prepared using such an electrochromic film as an electrochromic layer is considered to be one of the main development directions of building energy-saving glass. That is because such smart energy-saving glass can actively control the lighting and shading performance of glass, realize intelligence. Also, it consumes less electricity. And it is environmentally friendly.

Tungsten oxide powder for preparing a WO3-TiO2 electrochromic film is an electrochromic material that is very promising in information, electronics, energy, energy-saving building and national defense. WO3 is also a function material we are more familiar with. Some experts have successfully prepared a stable tungsten oxide gel with tungstic acid as a raw material, and prepared a tungsten trioxide electrochromic thin film doped with TiO2 by a sol-dip-coating method and an electrophoretic deposition method.

Yellow tungsten oxide powder for preparation of WO3-TiO2 electrochromic film is a promising inorganic electrochromic material, which may be used for producing electrochromic windows, and finally used in the field of smart building. Wherein some experts prepared TiO2 doped WO3 electrochromic thin film by sol-gel method, and studied the visible light transmittance before and after film discoloration.

Tungsten trioxide powder for producing a WO3-TiO2 electrochromic film is the most popular and the most studied inorganic electrochromic material. Wherein some experts have prepared WO3 electrochromic thin film doped with TiO2 by sol-gel method, and studied the effect of titanium content on the cycle life of the film.
