Cs0.32WO3, or cesium tungsten bronze, is often applied to produce heat insulating window glass (NIR shielding glass) as a near-infrared shielding material. According to the experts, cesium tungsten bronze nanoparticles can be prepared by solid state reaction under severe reaction conditions, such as hydrogen gas atmosphere above 800 °C, followed by energy consuming milling process. Also, cesium tungsten bronze nanocrystals can be fabricated directly by solvothermal reaction under mild conditions. Now, the latter method is often used.

But, how to manufacture heat insulating window glass using Cs0.32WO3 as a dingal nanomaterial? Cs0.32WO3 nano particles are often prepared into dispersed solution firstly. And then the dispersed solution is made into thermal insulation coating. Finally, the NIR shielding glass is obtained by coating the transparent coating on the surface of glass. So, there is no doubt that cesium tungsten bronze is popular for heat insulation of vehicles.
