Tungsten oxide powder, mainly tungsten trioxide powder, can be prepared into a WO3 film, and then be used to assemble an electrochromic glass, and finally be applied to building windows to achieve the purpose of heat insulation, heat preservation and energy conservation. Referring to electrochromism, experts say that in China, many universities, research institutes and enterprises have conducted research and industrialization in the field of electrochromic smart glass.

Tungsten trioxide powder is an important raw material for the preparation of an electrochromic layer in an electrochromic glass. According to experts, WO3 is the main electrochromic material for applying to assemble an EC glass. And Ni, V and TiO2 are often doped on the obtained WO3 film to improve its performance. Nowadays, electrochromic devices using WO3 as a functional material have gradually become industrialized.

Yellow tungsten oxide, or tungsten trioxide, is an important material for the preparation of an electrochromic layer of a smart glass window. With the gradual advancement of building energy conservation policies, energy-saving glass such as tungsten oxide electrochromic glass will be more and more widely used in the future.

WO3, also known as tungsten trioxide or yellow tungsten oxide, can be used to produce a smart glass window. The biggest feature of the obtained tungsten trioxide electrochromic window is that the color is dynamically adapted to the change of illumination, which can achieve the purpose of the most perfect energy conservation and comfort.
