CAS No：189619-69-0 

Appearance: blue powder,also can be customized  dispersions of different concentrations.

Main application: It can absorb infrared and ultraviolet, and it is also often used in ink.

Cesium tungsten bronze (Cs0.33WO3) is a non-stoichiometric functional compound with a special structure. It has low resistivity and low temperature superconductivity.
Cs0.33WO3 film has good infrared shielding performance and is often used as an infrared absorber. It is expected to replace the existing ITO conductive glass as a window material and can be used as a thermal insulation material. It has very attractive application prospects in the automotive and construction fields.

Cesium tungsten oxide nanopowder can absorb strongly in the near-infrared region (wavelength 800-1200nm) and has high transmittance in the visible light region (wavelength 380-780nm). At the same time, it also has a good absorption effect in the middle and far infrared region (8-10μm).

This material is currently the best performance automotive film, PVB insulation laminated film, and transparent insulation coating. Adding about 1.3 grams of nano-cesium tungsten oxide per square meter to the coating can achieve an infrared blocking rate of 950nm or more of 90%, a visible light transmittance of 550nm or more of 70%, and a haze less than 0.5%.

In addition, cesium tungsten bronze nano-powders are also widely used in laser marking, laser welding, greenhouses, photothermal diagnosis and treatment, infrared filters, etc.
