Cesium Tungstate Applied for Thermal Insulation Coating

Cesium tungstate may be used to prepare nano heat insulation slurry first, and then be applied for producing thermal insulation coating. As you may have known, the preparation of cesium tungstate raw materials is particularly important, which will affect the quality of subsequent slurry and coating. Therefore, experts have conducted in-depth research on the preparation method of cesium tungstate powder.

With the continuous improvement of technology, the previous methods of cesium tungstate powder requiring high temperature or explosive gases in the preparation process are slowly being eliminated. And the replacement is the economical and environmentally friendly preparation method. For example, some experts have proposed that using tungstic acid and cesium carbonate as the main raw materials to prepare cesium tungstate powder, in which the ratio of Cs/W substance is 0.01-0.35:1. And citric acid is used as the reducing agent. Besides, the solvent is water or the mixture of ethanol to water according to certain volume ratio. And then the cesium tungstate powder can be obtained by reacting in a reactor at 180-200°C for 1-3d.
