CsxWO3, Cs-doped tungsten bronze, is not only a tungsten bronze material, but also a type of near infrared shielding material. Tungsten bronze materials have attracted widespread attention for their excellent ferroelectric, piezoelectric, pyroelectric, and nonlinear optical properties. CsxWO3 has similar properties to that of tungsten bronze. Tungsten bronze is a series of nonstoichiometric compounds of formula of MxWO3 with special structure. The value of X is generally a value between 0 and 1. The specific value depends on the doping…

Cesium tungsten bronze powder is a near infrared shielding material, which may not only shield near-infrared light and ultraviolet light, but may also have high visible light transmittance. In other words, it “shields” heat in hot summer. And therefore, it reduces cooling fee. The cesium tungsten bronze may be prepared by ultrasonic chemical method, which has excellent performances of good dispersion and reproducibility. Moreover, the equipment for preparation process is simple. And the raw materials are relatively cheap and easy…

Nano cesium tungstate powder is a type of near infrared shielding material, which may be prepared by various methods. One of the preparation methods is described below. The cesium tungstate powder prepared by this method has the advantages of small particle size, uniform dispersion, less agglomeration and high purity. Also, it is conducive to industrial production. Preparation of Nano Cesium Tungstate Powder Step one: Dissolve ammonium paratungstate (APT) and cesium sulfate in citric acid solution and ethanol solvent, stir evenly,…

Cesium tungstate, as a near infrared shielding material, can be used for heat insulation in hot summer in the fields of construction glass and automotive glass. There is a method for preparing cesium tungstate, which can solve the problems of poor dispersity, poor heat insulation and low visible light transmittance of products prepared by prior preparation methods. Step one: Weight 1.47g sodium tungstate and 0.97g cesium carbonate, add 3mol/L citric acid solution and methanol reagent, stir evenly, and react at…

Cesium tungsten bronze nanopowder is a type of near infrared shielding material that can shield most of the solar radiation. The solar radiation is mainly ultraviolet (in the wavelength range of 200~380nm) and near-infrared radiation (in the wavelength range of 780~2500nnm). Cesium tungsten bronze (CsxWO3) is a mixture of hexavalent tungsten (W6+) and pentavalent tungsten (W5+). The W5+ makes the CsxWO3 more reducible. In CsxWO3, Cs+ is filled in the void formed by WO3. Therefore, cesium tungsten bronze crystals are…

Nano Cs0.33WO3 is a type of infrared thermal insulation nano material, which has high-efficiency near-infrared shielding performance. Meanwhile, it has high transmittance of visible light. It means that nano Cs0.33WO3 powder can shield most infrared rays while guarantees day lighting. However, since CS0.33WO3 particles are difficult to disperse in the solution, it is necessary to find a way to disperse the CS0.33WO3 particles in the solution to achieve the target of heat insulation. For the Cs0.33WO3 particles dispersed in the…

Nano cesium tungsten bronze is a kind of infrared thermal insulation nano material. It is also a kind of tungsten bronze material with rich structure. Tungsten bronze, MxWO3, can be doped with many kinds of positive ions, so that it has many excellent properties such as excellent catalytic performance, optical properties, high electrical conductivity, and excellent electrotransport properties. And therefore, it may be applied to many fields such as superconducting materials, thermal insulation materials and photoelectric materials. When M (the…

Cesium tungsten bronze is a type of infrared thermal insulation nano material, which can shield near-infrared light. Inside the metal, free electrons may be considered as static, and a large number of free electrons form plasma with natural vibration frequency. When the natural frequency is close to the frequency of the incident light, acute coupling occurs to form plasma wave. Then, the energy of the incident light is largely absorbed by metal as the plasma waves are in the process…

Cesium tungsten bronze nano powder, as a type of infrared thermal insulation nano material, is a raw material for preparing transparent heat insulation coating. The transparent heat insulation coating is mainly composed of a resin and a type of transparent semiconductor material (cesium tungsten bronze, etc.). These transparent semiconductor materials all have excellent optical properties. In other words, they have strong near-infrared shielding performance and high transmittance of visible light. Based on the optical performance of such coatings, they have…
