Nano Cesium Tungsten Bronze Preparation by Solvothermal Method

Scholars dissolved 400kg sorbitol in a jacketed reactor and dissolved it into tungstate and cesium sulfate, the ratio of the mass ratio of tungstic acid to cesium sulfate is 1 : 0.33tungsten carbide inserts , the quality of sorbitol is 3 times the total mass of tungstic acid and cesium sulfate, after high speed stirring 30 min, pump into homogeneous machine to carry on the cycle homogenization, after 60 min, the product is pumped into the high temperature reactor which has been heated to 150 °C, and the high pressure reactor speed is set to 180 r/min. When the above material is completely transferred to the autoclave, turn off the valve of the high-pressure reactor, gradually increase the temperature of the reactor to 350 degrees, and keep 600 min for 150 degrees, release the reaction product, adding deionized water to the filter press, washing with deionized water and absolute ethanol until the sulfate content is below 100 mg/kg, and the content of ethanol is more than 80%, the filter cake is placed in a vacuum oven for drying, and then mechanical pulverization and air flow grinding are carried out to obtain the target product - dark blue cesium tungsten bronze nanometer powder.
