Nano Cesium Tungstate Applied for Nano-ceramic Color Master

Nano cesium tungstate may be applied for preparing nano-ceramic color master. With the promotion of the application of color master, the preparation method of cesium tungstate has been paid more and more attention. For example, how to find a better preparation method of nanometer cesium tungstate powder? In this regard, experts have proposed a better preparation method of nanometer cesium tungstate powder, the specific steps are as follows:

1.0 According to n(cs)/n(w)=0.33:1, a tungsten salt (such as sodium tungstate) and a cesium salt (such as cesium hydroxide) are dissolved in a citric acid solution (concentration of 1.5mol/L) and alcohol solvent (isopropyl alcohol). After stirring uniformly, the reaction is carried out at 180-200°C for 2-3 hours to obtain a mixture of tungsten and cesium;

2.0 Add appropriate amount of urea to the mixture obtained in step 1.0, adjust the pH of the reaction solution to 3-5, set the reaction temperature of 50-80°C, stir until the urea is completely dissolved;

3.0 The mixed solution completely dissolved in step 2.0 is washed with argon gas, and subjected to chemical reaction under ultrasonic irradiation for 7-6 hours under the protection of argon gas at 70-90°C to obtain colloidal precipitate;

4.0 The colloidal precipitate was aged for 4-24 hours, then filtered, washed, dried, and finally calcined to obtain nano cesium tungstate powder.
