Nano CsxWO3, or nano grain size cesium tungsten bronze, may be used in the preparation of thermal insulation dispersion, which may be applied in the field of heat insulating architectural glass.

Nano CsxWO3, or nano cesium tungsten bronze powder, may be applied for preparing thermal insulation dispersion liquid. And therefore, such dispersion liquid of high heat insulation performance may be applied in building glass or auto glass.

Nano CsxWO3, or cesium tungsten bronze nano particles, may be used to produce near infrared shielding material for applying in architectural glass. Some experts have synthesized Cs0.32WO3 nano powder by hydrothermal method setting the Cs/W ratio of raw material to 0.5, and using D-malic acid as a reducing agent, at 24h, 48h and 72h at 175°C. Then, the powder obtained was tested by ultraviolet-visible-near-infrared diffuse reflection absorption spectroscopy.

The near-infrared shielding property of nano CsxWO3 for preparing infrared thermal insulation nano material is related to the crystallinity of CsxWO3 powder. After numerous experiments, the experts discovered this conclusion. Moreover, they also found that the Cs0.32WO3 sample obtained at a Cs/W ratio of 0.5 has a high concentration of free carriers. At this time, the crystallinity is the highest and the near-infrared shielding performance is optimal.
