Nano grain size cesium tungsten oxide is a blue-black powder with uniform particle size and high crystallinity that may be applied for producing thermal insulation dispersion. According to experts, cesium tungsten oxide nano powder is easily dispersed in polar and non-polar solvents. The obtained dispersion is a new type of dingal dispersion with excellent optical properties, which has blocking rate of up to 95% in the near-infrared region (visible light transmittance of 70%), and a good absorption effect in the…
