Cesium tungstate powder may be applied for preparing ceramic microsphere. With the promotion of application of this kind of ceramic particle, the preparation of cesium tungstate nano powder is more important. In this regard, experts began to consider how to simplify processing steps and reduce processing time. In addition, experts also consider the need for a simple process. Based on this, experts have found that the following nano cesium tungstate powder processing process can be satisfied. The preparation process mainly includes the following steps:

Step one: The reaction amount of ammonium metatungstate and cesium nitrate is dissolved in deionized water. The solution is dried to obtain powder. And the obtained powder is further pulverized to obtain a mixed powder of tungsten and cesium;
Step two: Add tungsten and cesium mixed powder to the reaction kettle, adding sorbic acid thereto, stirring at 300°C for 5h, the mass of sorbic acid is 3 times the mass of the mixed powder 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 then pulverized by a jet mill to obtain nano cesium tungstate powder; The drying time is 25min.
