A Method for Preparing Cesium Tungsten Bronze Nanopowder for Glass Curtain Wall Thermal Insulation Film
The expert introduced a preparation method of cesium tungsten bronze with low energy consumption, low cost, easy operation and good environmental protection. Also, it is suitable for large-scale industrial production. The processes include the steps as following as:
Step One: Weigh the main raw materials --- tungstic acid and cesium salt, and the molar mass ratio of the two is controlled at 1:0.01-0.1;
Step Two: The tungstic acid and the cesium salt are pulverized by a pulverizer and mixed;
Step Three: The mixed powder after pulverization is calcined in a sintering furnace under the protection atmosphere;
Step Four: The reaction product is repeatedly washed, and after drying and pulverization, the target product is obtained.
Among them, the cesium salt is one of cesium carbonate, cesium hydroxide, cesium chloride, and cesium nitrate.
