Cs0.32WO3 for preparing heat insulation coating is also known as cesium tungsten bronze with excellent near-infrared absorption performance, and relatively stable chemical and physical properties. It is these excellent properties make the heat insulation coating made of Cs0.32WO3 nano particles have the characteristics of high heat insulation performance and high visible light transmission. You know, if the free carrier content in the cesium tungsten bronze structure increases, the near-infrared absorption performance of the resulting powder will be stronger.

But do you know why the chemical and physical properties of Cs0.32WO3 nano powders are relatively stable? The chemical and physical properties of Cs0.32WO3 nanopowder are relatively stable because the cesium ion radius is 0.17nm and the grain size of tungsten bronze hexagonal tunnel is 0.163nm. That is to say, the two are similar in grain size, and Cs + can be stably embedded in the hexagonal tungsten bronze tunnel, so that it is not easily lost in the formed cesium tungsten bronze structure.
