CsxWO3 powder, or cesium tungsten bronze powder, may be applied for preparing thermal insulation dispersion. How to prepare? Some experts use sodium tungstate and cesium sulfate as raw materials to prepare transparent nano aqueous dispersion of cesium tungsten bronze by hydrothermal method. And experts have found that the obtained dispersion of nano grain size cesium tungsten bronze has excellent properties such as thermal insulation property, high transparency, excellent dispersion property and weather resistance.
The experts also blended the obtained cesium tungsten bronze transparent nano aqueous dispersion with aqueous resin to prepare transparent heat insulating coating. And they found that, compared with the cesium tungsten bronze nanopowder, the surface polarity of the particles which may occur in the subsequent blending process was avoided as the aqueous phase dispersion was first prepared, and the redispersion was difficult. Also, the compatibility of the water-based resin is good enough. It verified the dispersion performance of CsxWO3.
