Cesium tungsten bronze nanopowder is often used to prepare heat-insulating anti-explosion coating. This is because the cesium tungsten bronze nano-functional particles have excellent near-infrared absorption properties, which can make the car coating film or the architectural coating film exhibit excellent thermal insulation properties, thereby protecting the interior of the car or house from excessive heat radiation. According to statistics, in the hot summer, such a heat-insulating coating film can reduce the air-conditioning demand in the car by 60%. And the shielding rate of solar radiant heat is as high as 83%.

With the promotion and application of office thermal insulating film, more and more experts and scholars have begun to pay attention to cesium tungsten bronze nanopowder - a new type of environmentally friendly functional material with excellent near-infrared shielding performance. For example, they began to pay attention to the question - how to prepare cesium tungsten bronze nanoparticles?

Cesium tungsten bronze nanopowder for glass dome thermal insulating film can be synthesized by sol-gel method using tungsten powder, H2O2 and CsCl as raw materials. For example, the experts prepared the Cs0.33WO3 powder by such a method with excellent near-infrared shielding properties. In the process, they explored the effect of dispersant and different calcination conditions on the structure and properties of the prepared cesium tungsten bronze nanoparticles. And they also used X-ray diffractometer, transmission electron microscope, scanning electron microscope, X-ray energy spectrometer, X-ray photoelectron spectroscopy, ultraviolet/visible/near-infrared spectroscopy and other instruments to characterize the phase, microstructure, elemental composition and optical properties of the synthesized cesium tungsten bronze.

Cesium tungsten bronze nanopowder is known as the most suitable functional material for production of dining room thermal insulating film. So nano particle size cesium tungsten bronze has attracted much attention in recent years. For example, to study the optical properties of cesium tungsten bronze, the transmittance spectra of the as-prepared dining room thermal insulating film were studied.
