Cs0.33WO3, which is also known as cesium tungsten bronze, is a new type of dingal material that shields near-infrared light through absorption mechanism. Its application in smart glass thermal insulating coating has already attracted great attention. While do you know why the synthesis of cesium tungsten bronze is mostly based on the solid-state reaction method in a high-temperature reducing atmosphere?

According to the experts, this is because the particle size of Cs+ ions is relatively large, so when Cs+ ions are incorporated into the hexagonal tunnel, the octahedral frame structure of tungsten hexaoxide (WO6) will be deformed, and such deformation will cause the particle size and morphology of the CsxWO3 in reduced state are more difficult to control. Therefore, so far, most of Cs0.33WO3 nano particles for preparing smart glass thermal insulating coating have been prepared by a solid-state reaction method under a high-temperature reducing atmosphere.
