Cesium Tungstate Nanopowder Applied for Nano-ceramic Color Master

Cesium tungstate nanopowder may be applied for preparing nano-ceramic color master, which is more and more widely used in many fields. So, the preparation of nano grain size cesium tungstate is attracted more attention. In this regard, experts proposed a preparation method of nanometer cesium tungstate, comprising the following steps:

1.0 The reaction amount of ammonium paratungstate as a tungsten raw material and cesium hydroxide as a raw material of cesium are dissolved in a solvent of isopropyl alcohol, and the solution is dried (spray-dried) to obtain powder, and the obtained powder is further pulverized (ball milled pulverizing) 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 performance, and tetraethylene glycol as a reaction solvent was added thereto and stirred at 200°C for 2 hours, and the mass of the reaction solvent was 1.7 times the mass of the mixture of tungsten and cesium;

3.0 The reaction product in step 2.0 is separated (centrifuged), washed with deionized water or ethanol, dried, and pulverized by a jet mill to obtain nano cesium tungstate. Among them, the air pressure of the air bag of the crushing chamber of the jet mill is 0.7MPa, and the speed of the classifier of the jet mill is set to 3000r/m.
