WO3 powder may be used to prepare a transparent heat insulation glass coating. It is well known that glass curtain walls are applied to more and more urban buildings due to their aesthetics. Although the glass curtain wall is beautiful, it has shortcomings - fast heat dissipation, that is, poor heat preservation property. Therefore, in the cold winter, the glass curtain wall is not as good as the common brick wall.

In recent years, relevant institutions have developed a new result: a new type of transparent thermal insulation coating that can help the glass to have the ding of warm winter and cool summer. Such glass coating is made of nano semiconductor material, such as nano grain size tungsten oxide, by inorganic doping technology. Under the premise of not reducing the transparency of the glass, it can reduce the room temperature of 3°C-9°C in the summer, and can increase 2.5°C-5°C in the winter. At the same time, the price of such smart coating is lower than that of the imported glass film. And it is convenient to construct. It can be directly sprayed, and quickly dried to form a film. And thus, heat insulating coating of tungsten oxide nanoparticles is more and more popular.
