Violet tungsten oxide, or WO2.72, can be applied for preparing heat-ray shielding dispersion. And the prepared dispersion is often used to produce heat-shielding coating. And then the heat insulation coating has a wide application in the glass windows and glass doors of buildings.

Violet tungsten oxide, one of the tungsten oxide materials, is often discussed and studied on properties, preparation methods and applications. You know, WO3, which consists of perovskite units, is one of the most attractive candidates for photothermal conversion because of its suitable band gap (2.62 eV). And it is also known for its good optical absorption characteristics under ultraviolet light. While its photothermal conversion ability in near-infrared region is inferior to that of WO2.72. And therefore, WO2.72 is more well-known than WO3 when it comes to optical absorption properties. And there is no doubt that violet tungsten oxide is often applied for producing heat-ray shielding dispersion.
