Cesium Tungstate Powder Applied for Window Heat Insulation Film

Cesium tungstate powder may be used to produce window heat insulation film. With the promotion of this new type of environmentally-friendly heat insulation materials in the field of architectural glass, nano grain size cesium tungstate has attracted more and more attention, and therefore, its preparation has become more important. In this regard, experts said that the preparation of the raw material cesium tungstate nanopowder can be obtained by the method of full liquid phase and no high temperature heat treatment.

Specifically, tungsten chloride and cesium hydroxide are dissolved in absolute ethanol, and an appropriate amount of acetic acid is added thereto, and the system is crystallized in a closed high-pressure reactor at 200°C for 20 hours to obtain cesium tungstate nano powder. According to experts, the method is simple and easy to operate, and the process is short. However, the reactor pressure is too high, the reaction time is long, the cost of cesium hydroxide raw material is high, and therefore further research is needed to find out a more ideal preparation method.
