Cs0.32WO3 for producing transparent thermal insulating coating is cesium tungsten bronze with nano particle size. Cs0.32WO3 nanoparticles are known as near-infrared shielding nanoparticles. According to reports, Cs0.32WO3 nano powder should be prepared into suspension solution before being made into heat-insulating coating. Wherein, the preparation of cesium tungsten bronze suspension solution is very important. So, do you know how to prepare cesium tungsten bronze suspension solution?

Some experts put cesium tungsten bronze powder into a planetary ball mill, and added zirconia ball mill beads of 50 μm diameter for wet ball milling. Wherein, the selected solvent is an appropriate amount of potassium hydroxide added in deionized water. The pH value of the solvent is measured by pH measurement and adjusted to 8. The cesium tungsten bronze powder is added to the solution to make a 2wt% cesium tungsten bronze solution. The ball milling speed of the planetary ball mill is set to 120 rpm, and the ball milling time is 1-3 hours, to obtain cesium tungsten bronze suspension solution.
