Nano Cs0.33WO3 Applied for Ceramic Microsphere

Nano Cs0.33WO3, or nano particle size cesium tungsten bronze, for ceramic microsphere can be prepared by hydrothermal reaction using WCl6 and CsOH•H2O as raw materials. In this regard, the experts introduced the specific process of preparing cesium tungsten bronze powder:

1.0 Weigh a certain amount of cesium hydroxide dissolved in ethanol solution, weigh a certain amount of tungsten hexachloride dissolved in ethanol solution to prepare cesium hydroxide solution and tungsten hexachloride solution;

2.0 The prepared cesium hydroxide solution and the tungsten hexachloride solution are thoroughly mixed and stirred for 1 hour to obtain a reaction precursor liquid;

3.0 Transfer the reaction precursor solution into the reaction kettle, and hydrothermally react at 200°C for 1 day in an oven;

4.0 The precipitate obtained by the reaction was sequentially subjected to ultrasonication, water washing, alcohol washing, high-speed centrifugation 3 times, and naturally dried at room temperature to finally obtain a blue cesium tungsten bronze nano powder.
