Cesium Tungsten Oxide Particles Applied for Transparent Thermal Insulation Nanopowder

Cesium tungsten oxide particles, or cesium tungsten bronze, can be said to be transparent thermal insulation nanopowder as it can be used as a raw material of building heat-insulation film, heat-insulating coating and thermal insulation dispersion of high transparency. In other words, these heat insulation materials do not affect the passage of visible light, and they also have high thermal insulation property. Experts said that cesium tungsten bronze nanoparticles used in these thermal insulating material requires good dispersion. So, what is the dispersion of nanoparticles?

The dispersion of the nanoparticles is mainly to break up the agglomerated large particles by external shear force. A large number of tiny nanoparticles are produced during the dispersion process, which allows the particles to be better wetted by the dispersion medium. In order to better disperse the nanoparticles, a proper dispersing agent can be added to the dispersion medium to achieve a good dispersion effect. The dispersing agent is adsorbed on the surface of the particles, and the nanoparticles can be effectively dispersed by mutual repulsion and steric hindrance of the same charge.
