Nano Cs doped tungsten oxide, or nano cesium tungsten bronze, or nano Cs0.33WO3, may be applied for producing transparent thermal insulation material, which has excellent near-infrared shielding property. Due to its high transparency and high thermal insulation performance, in recent years, new heat insulation materials of cesium doped tungsten oxide nano particles have received more and more attention. Therefore, the experts are also more concerned about the problem that what kinds of raw materials are better for the production of Cs0.33WO3 dingal particles when other conditions are the same.

In this regard, some experts used WCl6, CsOH?H2O and Na2WO4?2H2O, Cs2CO3 as raw materials to synthesize Cs0.33WO3 materials, and compared the advantages and disadvantages of Cs0.33WO3 particles prepared by two materials. The research shows that the Cs0.33WO3 material prepared by using Na2WO4?2H2O and Cs2CO3 as raw materials has the advantages of excellent near-infrared shielding performance, simple preparation process, no pollution and low production cost. And it is more suitable for mass production.
