Nano Cs0.33WO3 may be applied for the manufacturing of a type of dingal masterbatch — thermal insulation masterbatch, which has excellent spectral selectivity and stability. It means that Cs0.33WO3 has good heat insulation effect, thereby reducing energy consumption. Nano Cs0.33WO3 powder can shield the near-infrared rays that carry heat in the light wave radiation, and the near-infrared shielding rate is more than 95% while guaranteeing that the transmittance of visible light reaches more than 80%. Functional masterbatch refers to the…

Cesium tungsten bronze may be applied for producing thermal insulation masterbatch — a kind of dingal masterbatch, which has the performance of shielding ultraviolet and near-infrared rays. It is also a kind of tungsten bronze material with excellent optical properties. When tungsten bronze is not doped with Cs+, the tungsten bronze is yellow in color. And when the amount of Cs+ is increased to a certain extent, the color of the cesium tungsten bronze will be changed into blue. It…

Nano Cs0.33WO3, or nano cesium tungsten bronze, is a type of near infrared shielding material. The photochromic property of CS0.33WO3 is derived from the fact that the small radius metal ions (Cs+) in the cesium tungsten bronze can enter and exit freely in the tunnel structure. Cesium tungsten bronze is also called Cs-doped tungsten bronze or Cs-doped tungsten oxide. And its doping method is reversible doping. When the doping amount of the metal ions (Cs+) is changed, cesium tungsten bronze…

Nano cesium tungsten bronze is a kind of near infrared shielding material. And the study of the selective transmittance mechanism of cesium tungsten bronze found: In cesium tungsten bronze, the valence state of tungsten is a mixture of hexavalent (W6+) and pentavalent (W5+), and charge carrier hopping between the two valence states are very likely to occur. When W5+ is oxidized to W6+, lattice vacancies will occur, and the electrons lost by tungsten will occupy vacancies and become color center.…

Cesium tungsten bronze is a kind of near infrared shielding material, which can be used for preparing heat-insulating coatings or thermal insulation films. Thus, it can be applied to architectural glass, such as glass curtain wall, glass door and glass window, as well as automotive film and other applications. Optical Properties of Cesium Tungsten Bronze Since cesium tungsten bronze has a special structure of internal tunnel and transport characteristics of carrier, it has many excellent optical properties such as electrochromism,…

Cesium tungsten bronze nano powder is Cs-doped tungsten bronze nano powder, which belongs to tungsten bronze material and near-infrared shielding material. When the cesium tungsten bronze powder is applied to shield near-infrared rays as window film or auto film, it can effectively shield near-infrared rays and ultraviolet rays. Also, this kind of film can guarantee day lighting as it has high transmittance of visible light. Tungsten bronze can form different structures such as cubic structure (CTB), tetragonal structure (TTB), intergrown…

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,…
