Cesium tungsten bronze powder, mainly nano grain size cesium tungsten bronze, may be used in the preparation of a new type of thermal insulation paper, which is transparent with excellent near-infrared shielding performance and thermal insulation performance. In recent years, some experts have prepared CsxWO3 at 200°C by solvothermal reaction using WCl6 and CsOH as raw materials.
These experts mainly studied the transmission spectrum of heat insulation film of cesium tungsten bronze nanopowder. They found that the CsxWO3 film has good near-infrared shielding properties. That is to say, the CsxWO3 film has a certain shielding effect on the near infrared rays in the range of 800-2500nm. However, at present, there are not many studies on the specific application of CsxWO3 near-infrared shielding performance (insulation) and the effect of cesium (Cs) content on the near-infrared shielding and thermal insulation properties of cesium tungsten bronze nano powder, which means that this aspect is still very promising.
