WO3 powder may be used to prepare a transparent thermal insulation coating and then be applied to architectural glass to obtain a heat-insulating energy-saving glass. That is because the raw material tungsten trioxide powder, more accurately, WO3 nanopowder is a material with special spectral selectivity - high shielding ratio in the infrared region, high transmittance in the visible region, and high absorption rate in the ultraviolet region.

Tungsten oxide energy-saving glass has the following technical features: nano-technology is applied to coat a uniform tungsten oxide nano coating on the surface of the glass, which can shield heat from entering the room through the glass doors and windows. Through the nano coating, the glass doors and windows are blocked to conduct heat energy indoors and outdoors, combined with the sealing ding of doors and windows, thereby reducing energy consumption. Through nano coating, the glass can shield infrared rays, reducing the transmission of indoor and outdoor thermal energy caused by radiation. With a strong film layer, the glass has good chemical stability, high temperature resistance, corrosion resistance, oxidation resistance and long life.
