Cs0.32WO3 is the mainly new type of nanomaterial for preparing window thermal-insulation film with excellent heat-shielding performance. According to the experts, the bead milling of Cs0.32WO3 coarse powder can be performed in aqueous solution in the absence of extra stabilizers. And the resulting Cs0.32WO3 nanoparticles are stabilized in aqueous solution via electrostatic repulsion mechanism, owing to their electric double layer.

Cs0.32WO3 for preparing coating glass is known as cesium tungsten bronze with heat shielding property. According to the experts, Cs0.32WO3 nano powder also has NIR photothermal conversion property. Some experts have obtained the Cs0.32WO3 powder of mean hydrodynamic diameters of 1,310, 250, 180, and 50 nm before grinding and after grinding for 1, 2, and 3 h, respectively. Their NIR photothermal conversion property in the aqueous dispersions was examined at a fixed particle concentration of 0.008 wt.%. For the samples before grinding and after grinding for 1 and 2 h, 5 wt.% of PEG 6000 was added to avoid the occurrence of precipitation.

Cs0.32WO3 is well known as a near-infrared shielding material for preparing sun protection glass. Well, do you know how to obtain the zeta potential and mean hydrodynamic diameter of Cs0.32WO3 nanoparticles? And how to get many other important information such as the content of the contaminant ZrO2?

Cs0.32WO3 is often prepared into heat insulation coating, which is mainly applied for producing heat insulation window glass with high near-infrared shielding performance. Wherein, Cs0.32WO3 can be synthesized by a high-temperature carbothermal synthesis method using cesium carbonate and tungstic acid as starting materials. And the prepared Cs0.32WO3 powder has suitable grain size and crystallinity.
