Cesium tungsten oxide with the formula of Cs0.33WO3 is well-known as a near-infrared shielding material for preparing green building glass curtain wall. Also, Cs0.33WO3 nano powder is known to all as a nano material with near-infrared photothermal conversion property.

Cesium tungsten oxide for preparing smart window glass is mainly hexagonal Cs0.33WO3 nanoparticles that could exhibit excellent near-infrared absorption performance with a mean hydrodynamic diameter of about 50 nm as the maximum absorption band was highly sensitive to the particle’s size.

Cesium tungsten oxide such as Cs0.33WO3 is a new type of near infrared shielding material for preparing many transparent heat insulation products such as heat insulation film, heat insulation dispersion, heat insulation coating. And these functional products are mainly applied to exterior glass doors, glass curtain wall, and exterior glass windows of buildings and cars. For these applications, it requires cesium tungsten oxide has best near-infrared shielding performance. But how to get such a smart coating?

Cesium tungsten oxide powder for preparing nano heat insulating coating is a new type of functional material with excellent near-infrared shielding properties. And the cesium tungsten oxide used is often Cs0.33WO3 nano powder. You know, the Cs0.33WO3 powder should be processed by ball-milling into nano particles for applying to produce nano heat insulating coating. Well, do you know what the SEM of Cs0.33WO3 looks like before and after ball-milling, respectively.
