Cesium tungsten oxide may be applied for producing thermal insulation dispersion, which may effectively shield thermal radiation in the near-infrared and far-infrared regions while the dispersion still remains transparent in the visible region. As the cesium tungsten oxide nanoparticles have excellent super dispersion property, such dispersion has higher visible light transmittance than other types of dispersion under the same heat insulation effect.
Therefore, the dispersion of nano grain size cesium tungsten oxide has a selective shielding property to the infrared region, and can block external heat from entering the building in the summer to some extent. And in winter, it can also prevent heat loss in the room, thereby saving energy. In addition, the dispersion has the characteristics of long service life, excellent weather resistance, acid resistance, alkali resistance, corrosion resistance, impact resistance and scratch resistance. In a word, such thermal insulating dispersion of nano cesium tungsten oxide is a good choice for high heat insulation.
