The experts introduced a preparation method of cesium tungsten bronze nanopowder for office thermal insulating film, and the preparation steps are shown as following as:
Step One: Weigh the cesium chloride and ammonium tungstate according to the atomic ratio of 0.30-0.32, placed in hydrogen peroxide to dissolve it, and stirred at 60-80 °C to obtain the suspension, and then the prepared suspension was dried at 40-80 °C to obtain the cesium-tungsten mixture precursor.
Step Two: Mix the precursor with a certain amount of ethylene glycol, then ground in a ball mill for 10 to 60 minutes; wherein the solvent is used in an amount of 0.5 to 1.5 times the mass of the precursor powder.
Step Three: The prepared substance is placed in a closed reaction vessel equipped with a stirring device for heat treatment at a temperature of 150 to 300 °C for 2 to 10 hours.
Step Four: Separate the above-mentioned materials and washing them with ethanol and deionized water, and then drying in an oven at 40-80 °C to obtain cesium tungsten bronze nano powder.
