Nano Cs doped tungsten oxide, or nano particle size Cs0.33WO3, or nano grain size cesium tungsten bronze, may be used to produce a new type of transparent thermal insulation dispersion liquid, and be applied for the preparation of a heat insulating film, and finally be applied to architectural glass to achieve thermal insulation performance. Among them, experts said that the dispersion of cesium tungsten bronze nanoparticles can be prepared by ball milling.

Specifically, the expert disperses a mass of 1.8g of cesium tungsten bronze nano powder which has been subjected to nitrogen heat treatment for 2 hours in 30mL of an aqueous solution, adjusts the pH with NaOH and HCl, and transfers the dispersion into a 50mL polyurethane ball mill jar, and adds a certain amount of zirconium oxide (ZrO2) ball for ball milling. This process uses a planetary ball mill with a speed set to 210r/s. Among them, the ball/dispersion mass ratio is 5:1, the ball size is 1mm, the ball milling time is set to 3h, and the pH is 7.
