Tungsten trioxide may be used as a near-infrared shielding material as it has good optical properties. In other words, WO3 has photochromic effect. The shielding material mainly refers to the material that has a certain shielding performance to the ultraviolet ray and the near infrared ray. And the application scope of WO3 will be expanded gradually as people need to reduce energy consumption and improve human body comfort.
There are many methods for preparing tungsten trioxide, including gas-liquid reaction method, precipitation method, sol-gel method, hydrothermal synthesis method, microemulsion method, and template method, etc. Different preparation methods may be used to prepare tungsten trioxide with special morphology. And it is the special structure and morphology that the synthesized tungsten trioxide powder has some new physical and chemical properties.
