Cs doped tungsten oxide powder may be applied for preparing infrared ultraviolet shielding material, such as, nano transparent heat insulating coating, which has excellent visible light transmittance, infrared shielding rate and ultraviolet shielding rate. Generally, the visible light transmittance of the nano transparent thermal shielding coating of cesium doped tungsten oxide nano powder prepared in China is generally higher than 70%. The infrared shielding rate is higher than 85%, and the ultraviolet shielding rate is higher than 99.5%.

According to experts, although the above-mentioned thermal insulation coating of nano grain size cesium doped tungsten oxide conforms to the national standards for heat insulating transparent coatings, its performance can be further improved. The visible light transmittance and the infrared shielding rate of the coating can be further improved to obtain a more outstanding thermal insulation coating, which is more conducive to the development of heat insulating material industry. In other words, experts are paying more and more attention to such heat insulation material – cesium doped tungsten oxide.
