Yellow tungsten oxide powder, or tungsten trioxide powder, is an inorganic electrochromic material that can be made into an electrochromic film and assembled into a new type of energy-saving window - smart window for use in high-end cars and buildings. Such smart glass can not only play the role of heat insulation, but also save energy and reduce consumption.

WO3 powder is an important inorganic electrochromic material for producing a smart glass. Smart glass has a wide variety of applications, as you may have known.

Tungsten oxide powder is an inorganic electrochromic material, which can be produced into an electrochromic film and then be assembled into a smart glass. As you may have known, smart glass is a relatively recent development, which exists to make the building environment more comfortable and to help decrease energy loads.

Tungsten trioxide nanopowder is considered to be the most inorganic electrochromic material for large-scale application. According to experts, WO3 films can be used to assemble electrochromic devices with different structures and characteristics. These electrochromic devices enable a continuous, multi-color continuous change in transmittance and reflectance in the visible, infrared, and even microwave ranges.
