Nano yellow tungsten oxide may be applied for producing ceramic microsphere so that it has good heat resistance, nice weather resistance, and excellent dispersibility, etc. And thus, it may be used for producing heat insulating sheets or films. The visible light transmittance of the prepared heat insulating film is 50~75%, the infrared shielding rate is 90~99% and the ultraviolet shielding rate is 99%.
Compared with traditional ATO and ITO, the near-infrared shielding material using yellow tungsten oxide as raw material has high transmittance of visible light and higher near-infrared shielding rate; It can be used as a heat insulation material for window; It is not easy to fade with high thermal stability and good dispersion; Haze is lower than 0.5%; It does not shield communication electronic signals, which means that it has no effect on mobile phones, GPS navigation and other electronic devices. And therefore, its application will become more and more extensive.
