Cesium tungsten oxide particles, or cesium tungsten bronze, with a molecular formula of Cs0.33WO3, may be applied for producing thermal insulation dispersion liquid, and be used to architectural glass in the form of a thermal insulation film. Among them, some experts conducted experiments on the zeta potential and absorbance of Cs0.33WO3 dispersion at different pH.

Cesium tungsten oxide particles may be used to prepare infrared thermal insulation nano material, such as, architectural insulation films. The obtained heat-insulating film can shield most of ultraviolet rays in the sunlight. So, the building glass window can better avoid the fading and aging of indoor articles, and can also beautify the appearance of the building.

Cesium tungsten oxide particles, or cesium tungsten bronze particles, may be applied for producing near infrared shielding material such as thermal insulation dispersion. As is well known, infrared ray, also known as infrared radiation, thermal radiation or heat ray, is a part of non-ionizing radiation belonging to the invisible band. The infrared ray can be classified into near-infrared, mid-infrared and far-infrared. Among them, the near-infrared band is 780nm to 1400nm.

Cesium tungsten oxide particles are cesium tungsten bronze particles, which may be used to prepare infrared ultraviolet shielding material such as transparent building heat insulation film. As we all know, the infrared radiation energy accounts for 46% of the solar radiation energy, which is harmful to the human body to some extent. Although the proportion of ultraviolet light in sunlight is small, only 3%, but it does great harm to human body.
