CsxWO3, as a near-infrared shielding material, can be prepared by a molten salt method at an air atmosphere of 400 °C. What is CsxWO3? It is cesium tungsten bronze. Why use the molten salt method? Because the reaction temperature of the conventional solid-phase method is too high. And it requires an atmosphere. So, the molten salt method is selected to save production costs.

Tungsten trioxide, or WO3, has great potential in the research and production of new automotive smart glass. According to the experts, it is WO3 nano particles that may change an ordinary glass into a smart glass. And the transparency of such a glass may be changed to play a role of heat insulation. And therefore, it reduces the temperature inside the car, reduces energy consumption and harmful UV radiation.

Experimental studies have found that Cs0.32WO3 has excellent near-infrared shielding properties, so it can be used to prepare functional film for applying to surfaces of ordinary glasses. And therefore, the obtained smart window can reduce energy consumption and carbon dioxide emissions, and partially solve energy crisis. Wherein, Cs0.32WO3 is nano particle size cesium tungsten bronze. And it is often applied to sunrooms, office buildings, hotels, shopping malls and many other buildings.

Cs0.32WO3, or cesium tungsten bronze, is a functional compound of specific structure of oxygen octahedral.
