Nano cesium tungsten bronze powder is a kind of transparent thermal insulation material, which is mainly applied in the form of thin film on heat insulation glass, such as, auto glass, and building glass, etc. Nano cesium tungsten bronze powder may be prepared by hydrothermal method. By hydrothermal reaction, using cesium carbonate as a source of cerium and tungstic acid sol as a source of tungsten, nano grain size cesium tungsten bronze is obtained with high absorbance of 1.96 for…

Cesium tungsten oxide is a choice of transparent thermal insulation nanopowder. Sample Characterization of Cesium Tungsten Oxide 1. X-ray diffractometer (XRD) was used to identify the crystal structure of cesium tungsten oxide nanopowder. 2. Scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to observe the morphology of cesium tungsten oxide powder. 3. Laser particle sizer was used to analyze particle size distribution of the powder. 4. The ultraviolet-visible spectrophotometer was used to characterize the near-infrared shielding performance…

CsxWO3, Cs-doped tungsten bronze, is a kind of transparent thermal insulation nanopowder. The Cs-doped tungsten bronze is usually a type of low resistivity material, in which there are generally a large number of free carriers, so that it has strong absorption on free carriers. And the absorption coefficient of free carrier (α) has a positive relationship with free carrier concentration and square of wavelength of absorbed light. Therefore, when the content of cerium (Cs) in Cs-doped tungsten bronze increases, the…

One type of transparent thermal insulation nanopowder is cesium tungstate. The cesium tungstate nanopowder is an inorganic nanopowder that has the best absorption capability in the near infrared rays so that it has wide applications in many fields such as construction and industry. There are many ways preparing nano-powders, which can be roughly divided into solid phase method, vapor phase method and liquid phase method. Some are synthesized by two or more methods. However, there are not many methods for…

Cesium tungsten bronze is one of many kinds of transparent thermal insulation nanopowder with good near-infrared shielding performance, which may be prepared by solvothermal process. Preparation of Nano Cesium Tungsten Bronze by Solvothermal Method The cesium hydroxide, tungsten hexachloride and ethanol are mixed, then a certain amount of acetic acid is added to the mixture, and then transferred to an hydrothermal reactor to react at a temperature of 200°C for 10 hours to obtain cesium tungsten bronze with particle size…

Nano Cs0.33WO3 is a type of infrared ultraviolet shielding material, which means that it can shield ultraviolet rays and near-infrared rays. It can be prepared by hydrothermal synthesis using Cs2CO3 and Na2WO4 as raw materials, and citric acid as a reducing agent. Preparation of Cs0.33WO3 Coating The Cs0.33WO3 particles were dispersed in an aqueous solution to obtain Cs0.33WO3 dispersion slurry, and 2.5% polyethylene glycol-400 was added as a wetting agent, and then 1mm zirconia balls were used for ball milling.…
