Tungsten oxide powder may be applied for producing a building glass energy saving coating, which has high permeability to visible light and good shielding performance to infrared light or thermal radiation. Such transparent heat-insulating coating is mainly composed of semiconductor metal oxide nanoparticles which are spectrally selective to sunlight, namely tungsten oxide nanoparticles, and transparent resin.

WO3 powder may be used to prepare a building glass energy saving coating. The prepared coating has a simple construction process – it can be dried and formed into a film in 20-120 minutes with a long service life. Therefore, the popularization and application of heat insulation coating of tungsten trioxide nanoparticles is of great significance for the popularization of national energy-saving buildings, especially for energy-saving renovation of old buildings.

Tungsten trioxide powder may be used to prepare a building glass energy saving coating, which may be used for the heat insulation of glass curtain wall, glass doors and windows of hotel, office building and shopping mall, or for the heat preservation of cold regions in winter.

Nano yellow tungsten oxide may be used to prepare an environmentally friendly building glass energy saving coating, i.e., transparent thermal insulation and heat preservation coating. As you may have known, glass is the main source of energy loss in buildings. Up to 1/3 of the heat or cold air generated by air conditioners is lost through glass curtain walls, glass doors and glass windows, resulting in a huge waste of energy.
