Cesium Tungstate Applied for New Energy Saving Glass

Cesium tungstate for production of new energy saving glass is cesium tungstate (Cs0.33WO3) nanopowder that has very strong absorption in the near-infrared wave band (800-1200nm of wavelength) and in the ultraviolet wave band (180-380nm of wavelength). Also, cesium tungstate nanoparticles have high transmittance in the visible wave band (380-800nm of wavelength).

In a word, the new energy saving glass of cesium tungstate has strong heat shielding performance due to the above-mentioned excellent characteristics. And therefore, it has been widely used in heat-insulating field, such as automobile heat insulation film and architectural glass film. In this process, the Cs0.33WO3 nanoparticles should be first prepared into a suspension solution. And the experts have found that when the weight percent concentration of the cesium tungstate suspension solution is 0.03wt%, its absorption in the near-infrared light band and its transmittance in the visible light band are relatively good. So, why not choose such a glass for energy saving reconstruction of building?
