Nanometer cesium tungsten bronze may be applied for producing nano-ceramic color master. This is because the nano particle size cesium tungsten bronze powder has strong absorption properties in the near-infrared region at the wavelength range of 800-1200nm and high transmittance in the visible light region at the wavelength range of 380-780nm, so that a new dingal ceramic color master can be prepared.
At present, the new dingal nano ceramic color master of nano grain size cesium tungsten bronze powder has begun to be used in automotive film, PVB insulation film, transparent heat insulating architectural glass and other fields requiring high transparency and high heat insulation. As the color master has excellent dispersibility, the infrared shielding rate of 950nm is more than 90%, the visible light transmittance of 550nm is more than 70%, and the haze is less than 0.5% by adding about 1.3 grams per square meter in the coating.
