Cs0.32WO3 Nanoparticles Applied for Thermal Insulation Masterbatch

Cs0.32WO3 nanoparticles may be used to prepare thermal insulation masterbatch. The obtained masterbatch may be used to prepare a new transparent heat insulating material, which is more and more widely used in the fields of architectural glass and the like. Among them, some experts studied the relationship between different ball milling time and the average secondary particle size of Cs0.32WO3 particles. They found that the average secondary particle size of cesium tungsten bronze particles after ball milling for 3h, 6h, and 9h was 164nm, 149.6nm, and 257.2nm.

With the increase of ball milling time, the average secondary particle size of cesium tungsten bronze powder gradually decreased. The average secondary particle size increased after ball milling for 9 hours, which indicated that the proper milling time can effectively open the agglomeration of cesium tungsten bronze particles, to reduce average secondary particle size. Excessive ball milling exposes the active surface of the particles. While ball milling produces higher temperatures that destabilize the nanoparticles. And the secondary agglomeration appeared.
