You know, Cs0.33WO3 is also called cesium tungstate or cesium tungsten bronze, which is a new environmentally friendly dingal material with excellent near-infrared absorption properties, and is therefore often used to prepare smart glass thermal insulation coating. Well, do you know how to make cesium tungsten bronze nano particles stably dispersed in aqueous solution?

Some experts added 10 wt% cesium tungstate powder with a particle size of about 1-2 μm to the potassium hydroxide solution, and adjusted the pH value to a suitable value. And then zirconia ball beads with a diameter of 50 μm was used to perform wet ball milling. The milling time was 3 hours. And cesium tungstate nano particles with a particle diameter of 50 nm were finally obtained. Wherein, when the pH value is 8, the Zeta potential of the cesium tungstate nanoparticles reaches a maximum constant. At this time, the cesium tungstate nanoparticles are stably dispersed in an aqueous solution.
