Tungsten trioxide is a new type of nano functional material with high heat insulation and UV blocking rate, so it is often used to produce bedroom heat insulating glass coating. Such coating is safe and eco-friendly without toxic and harmful substances.

Tungsten trioxide is a new type of inorganic nano material with special optical properties, so it is often used to prepare living room heat insulating glass coating --- a new type of environmentally friendly transparent functional coating. As such a thermal insulation coating has the characteristics of high visible light transmittance, excellent heat insulation performance and low cost, it is expected to achieve large-scale applications. It means that tungsten trioxide is of great significance for building energy conservation.

Tungsten trioxide, as a new type of environmentally friendly functional material, is regarded as the most suitable raw material for preparing bathroom heat insulating glass coating. Therefore, more and more scholars have begun to study this new thermal insulation material. For example, to study the question --- how to prepare tungsten trioxide powder with controlled crystal plane growth.

WO3 film is the most suitable electrochromic film for the production of smart glass. It is reported that the electrochromic smart window assembled using WO3 film as an electrochromic layer material has eight advantages.
