Cesium tungsten bronze nanopowder is a type of infrared ultraviolet shielding material, which is also a kind of tungsten bronze nano material. Other tungsten bronze materials, such as potassium tungsten bronze, also have excellent near-infrared shielding performance.
The cesium tungsten bronze nanopowder can shield near-infrared rays while maintaining high transmittance of visible light. And therefore it is widely applied in the field of transparent heat insulation coatings.
Studies have shown that tungsten bronze has strong selection to light transmission. At the same time, tungsten bronze dispersion has weaker visible light absorption and smaller solar heat gain coefficient than that of ITO nano dispersion. Thus, the hexagonal tungsten bronze is considered to be an excellent transparent heat insulating material, and at the same time, the grain size of tungsten bronze powder influences the performance of tungsten bronze material. The light selective absorption ability is stronger if its size is smaller. Thus, it can be widely applied to the field of transparent heat insulation.
