Tungsten trioxide powder for preparing large area electrochromic glass is a cathode coloring material with durable electrochromic properties and a large light modulation range. Also, WO3 is a well-developed electrochromic material. Besides, it is more and more well-known as it is an environmentally friendly heat insulation material with high transparency. So, smart windows of tungsten trioxide are more and more widely applied in glass curtain walls and many other large area glasses.

Tungsten oxide is an inorganic electrochromic material that can adjust the visible light transmittance and solar radiant energy of large area electrochromic glass in accordance with human will. In other words, electrochromic technology provides a new solution for energy saving in modern buildings.

WO3 for preparing large area electrochromic glass is an inorganic electrochromic material. And tungsten trioxide is also a cathode coloring material in accordance with the coloring way. As you may have known, electrochromic glass is a functional glass, also a kind of smart glass, which not only can adjust the transmittance of visible light, but also has a shielding effect on infrared light in the colored state. In other words, such smart glass can play the role of heat insulation without affecting indoor lighting.

Yellow tungsten oxide can be prepared into a tungsten oxide film and then be used as an electrochromic layer material for assembling a large area electrochromic glass – a smart window for green building. Also, tungsten trioxide electrochromic film can be applied to produce display device and thermal control device. Increasing commercial applications make tungsten trioxide receive extensive research and more attention.
