Cesium Tungsten Bronze

Sales Cesium Tungsten Bronze

Cesium Tungsten Bronzes(Cs0.32WO3) is a near-infrared absorbing nano material with uniform particles and good dispersion. Cs0.32WO3 has excellent near-infrared shielding performance and high visible light transmittance. It has strong absorption in the near-infrared region (wavelength 800-1200nm) and high transmittance in the visible light region (wavelength 380-780nm).  We have the successful synthesis of highly crystalline and high purity Cs0.32WO3 nanoparticles through a spray pyrolysis route. Using sodium tungstate and cesium carbonate as raw materials, cesium tungsten bronze (CsxWO3) powders were synthesized by low temperature hydrothermal reaction with citric acid as the reducing agent.

What is Cesium Tungsten Bronzes (Cs0.32WO3) used for?

Cesium Tungsten Bronzes (Cs0.32WO3) are widely used as transparent heat insulating coating and membrane, such as transparent insulating window film, architecture coating. Cs0.32WO3 also applies for thermal chemical fiber, textile fiber and other high performance insulating media. Cesium Tungsten Bronzes have the application for Car pad pasting, PVB insulating membrane, laser marking, diagnosis treatment, infrared filter. Tungsten bronzes are also suitable materials for systematic studies of the dependence of the work function on composition and structure.
