Cesium Tungstate Powder Applied for Transparent Thermal Insulation Nanopowder

Cesium tungstate powder may be applied for producing transparent thermal insulation nanopowder. While what should be noted is that the obtained powder is not really transparent, but it is transparent when used to prepare thermal insulating materials such as thermal insulation dispersion, thermal insulation film and thermal insulation coating.

In addition, with the popularization and application of these thermal insulating materials, cesium tungstate has also received more and more attention. Therefore, the preparation of cesium tungstate nanopowder is even more important. Some experts have found that the following preparation process can greatly simplify the processing steps, reduce the processing time. Also, it is easy to operate.

A preparation process of nanometer cesium tungstate, comprising the following steps:

Step one: The reaction amount of ammonium metatungstate and cesium nitrate is dissolved in deionized water, and the solution is dried to obtain powder. The obtained powder is further pulverized to obtain a mixed powder of tungsten and cesium;

Step two: Add the mixture of tungsten and cesium to the reaction kettle, adding sorbic acid thereto, stirring at 240-460°C for 4-6 hours, the mass of sorbic acid is 2-4 times the mass of the mixture of tungsten and cesium;

Step three: The reaction product in step two is separated and washed with deionized water, then dried in a common oven, dried for 20-30min, and pulverized by a jet mill to obtain nano cesium tungstate powder.
