Cesium tungsten bronze is also known as cesium tungsten oxide, tungsten bronze, cesium tungsten and other names. Cesium tungsten bronze dispersion, also known as tungsten bronze dispersion, cesium tungsten dispersion.
Cesium Tungsten Bronze (Nano Cesium Tungsten Oxide, CTO, Cs0.33WO3) has the property of absorbing red and near-infrared rays. The absorption wavelength in the near-infrared region is 800-1200nm, and it has high transmittance in the visible light region (wavelength 380-780nm). The visible light transmittance of the thin film prepared by cesium tungsten bronze powder paste is over 71%, and the infrared light (800-2500nm) transmittance is over 13.5%.
Nano-cesium tungsten bronze powder is dispersed into a stable nano-slurry, that is, cesium tungsten bronze dispersion liquid, which can be added to the coating to make a transparent heat-insulating coating with near-infrared blocking. The dispersion solution is divided into suspension and emulsion. The cesium tungsten dispersion is to uniformly and stably disperse the cesium tungsten bronze powder particles in the liquid phase. The solid particles are called the dispersed phase, and the liquid phase is called the continuous phase. The infrared absorption peak of cesium tungsten near-infrared absorber is at 1200-1700nm, the absorption rate reaches 95%, and the absorption rate at 950nm-2000nm reaches more than 90%. The liquid made of cesium tungsten near-infrared absorber by dispersion process has good dispersibility, high transparency and low haze. At the same time, it is resistant to high temperature, does not oxidize, does not degrade, and has good weather resistance. Cesium tungsten near-infrared absorber dispersion is an excellent functional material for heat shielding, light filtering, anti-counterfeiting, and heat absorption.
Cesium tungsten bronze (Cs0.33WO3) is a non-stoichiometric functional compound with a special structure of oxygen octahedron, which has low resistivity and low-temperature superconductivity. The film made of cesium tungsten bronze (Cs0.33WO3) dispersion has good near-infrared shielding performance, and is expected to replace the existing ITO conductive glass, transparent heat-insulating coating, film; transparent heat-insulating window film, building coating; heat preservation Chemical fiber, textile fiber and other high-performance heat insulation media. The film made of cesium tungsten bronze (Cs0.33WO3) dispersion can be used as a window material, which can be used as a good near-infrared heat insulation material, and has a good application prospect in the fields of automobiles and buildings.
