Cesium tungstate is a type of inorganic nanoparticles with outstanding near-infrared absorption and visible light transmission properties so that it may be applied for producing thermal insulation masterbatch. And the obtained masterbatch has been widely used in the field of transparent heat insulation films. And therefore, such new thermal insulation material of cesium tungstate nanoparticles is widely used in industries such as architectural glass and automobile glass.

Therefore, in order to prepare nano grain size cesium tungstate powder with good optical property, the researchers have adopted many methods and achieved good results. However, at present, there are still many shortcomings in the production process of nano particle size cesium tungstate powder. And thus it is difficult to apply such thermal insulation material in a wider field due to high cost. While as the research progresses, the experience of the predecessors is continuously summarized, and more and better preparation methods will continue to appear in the future.
