Cesium tungsten bronze (CsxWO3) CAS NO. 189619-69-0 

Cesium tungsten bronze (CsxWO3) is a functional compound with a special oxygen octahedral structure and low electrical resistivity and low-temperature superconducting properties. In addition, CsxWO3 film has excellent near-infrared shielding performance and is expected to replace existing ITO conductive glass as a window material. It can be used as a good near-infrared insulation material and has great potential for application in the automotive and construction fields.

Infrared light, especially near-infrared light, has a significant thermal effect, which can easily cause temperature rise, resulting in an increase in temperature indoors or in a car. Therefore, in buildings, especially in building glass and automotive materials, film should be applied to isolate infrared light.

The use of film not only provides thermal insulation, but also prevents solar radiation and skin diseases, greatly prolonging the use time of car decorations, while keeping the indoor temperature relatively constant. At present, publicly available near-infrared shielding materials generally refer to a type of functional thin film material that has strong absorption or reflection of near-infrared light without affecting its visible light transmission. As a transparent insulation material, it has a wide range of application prospects in the fields of green building energy conservation and automotive glass insulation.

Near infrared shielding materials generally refer to a type of functional thin film material that has strong absorption or reflection of near-infrared light without affecting its visible light transmission. As transparent insulation materials, they have a wide range of application prospects in the fields of green building energy conservation and automotive glass insulation. The inorganic materials with strong near-infrared absorption or reflection properties that have been reported so far mainly focus on conductive oxides, such as tin antimony oxide (ATO), indium tin oxide (ITO), and zinc aluminum oxide (AZO).

Cesium tungsten bronze (CsxWO₃) has been discovered as a new material with near-infrared shielding and thermal insulation properties, and has begun to be applied in the market. CsxWO3 film can shield near-infrared light with wavelengths greater than 1100 nm. After coating the glass surface with CsxWO₃ film, its near-infrared shielding and thermal insulation properties increase with the increase of cesium content in CsxWO₃. Among them, the glass coated with CsxWO₃ film has the best thermal insulation performance, with a thermal insulation temperature difference of up to 13.5 ℃ compared to blank glass. Therefore, it has better near-infrared shielding performance and is expected to be widely used as smart windows in the fields of building and automotive glass insulation.

The cesium tungsten bronze dispersion developed by the kpolychem team has a thermal insulation rate of over 90%, visible light transmittance of over 80%, and haze of less than 0.6. The addition method is simple, just follow the original production process. For more information, please consult our team and product details.
