Nano Grain Size Cesium Tungstate Applied for Nano-ceramic Color Master

Nano grain size cesium tungstate may be applied for producing nano-ceramic color master. And the preparation of nano cesium tungstate powder is more concerned with the promotion of such color master. For example, an expert proposes a method for preparing cesium tungstate nano powder, which comprises the following steps:

1.0 The reaction amount of ammonium tungstate and cesium nitrate was dissolved in deionized water. The solution was oven-dried to obtain powder, and the obtained powder was further mechanically pulverized to obtain a mixed powder of tungsten and cesium.

2.0 The tungsten and cesium mixed powder was placed in a closed reaction vessel with stirring, and triethylene glycol as a reaction solvent was added thereto. Then, the reaction was undergone at 350°C for 5h, and the mass of the reaction solvent was 1.5 times the mass of the tungsten and cesium mixed powder;

3.0 The reaction product in step 2.0 was separated and washed with deionized water or ethanol, dried, and pulverized by a jet mill to obtain nanometer cesium tungstate. The air pressure of the air bag of the crushing chamber of the jet mill was 0.75MPa, and the speed of the air pulverizer classifier was set to 5000r/m.
