Cs0.32WO3 particles, or cesium tungsten bronze nano particles, may be used to prepare near infrared shielding material. And the prepared heat insulation material is a transparent heat insulating material, which has been more and more widely applied to glass to achieve good effect of heat insulation and high visible light transmittance. Experts say that ball milling will have a certain effect on the visible-near-infrared transmittance of Cs0.32WO3 nano particles.

Cs0.32WO3 particles may be applied for producing infrared ultraviolet shielding material such as transparent thermal insulation coating. According to experts, transparent thermal insulation coating is a new type of coating that has the characteristics of high thermal insulation and excellent visible light transmission. However, at present, there is no uniform product standard and testing method at home and abroad.

Experts said that ball milling is beneficial to disperse the Cs0.32WO3 particles, so that the infrared thermal insulation nano material prepared by such particles has better near-infrared shielding performance. The expert used 1mm zirconia grinding ball. And the ball was milled for 3h under the condition that the mass ratio of the ball to the dispersion was 5-6. And finally the cesium tungsten bronze particles with uniform size and the dispersed stable Cs0.32WO3 dispersion were obtained.

Cs0.32WO3 particles may be used to prepare transparent thermal insulation material, such as thermal insulation coating and thermal insulation film, and thus be applied to architectural glass. Among them, the raw material particles used are cesium tungsten bronze nanoparticles, whose particle size is similar to that of colloidal particles. So, the dispersion stability of Cs0.32WO3 nanoparticles can be studied by the stability theory of colloids, such as the theory of electrostatic steric stabilization. So, what is the theory of electrostatic steric stabilization?
