Cesium Tungsten Oxide Particles Applied for Ceramic Microsphere

Cesium tungsten oxide particles may be used for producing ceramic microsphere, and the obtained ceramic granules can be used for preparing heat insulating materials such as transparent heat insulating films, and thus be used in building glass. Among them, the raw material cesium tungsten oxide powder is cesium tungsten bronze nanoparticles. Since the dispersion stability of the nanoparticles affects the quality of the thermal insulation film - thermal insulation performance, experts say that it is necessary to study the dispersion stability of nanoparticles.

So, how to study the dispersion stability of nanoparticles? Since the particle size of the nanoparticles is similar to that of the colloidal particles, the dispersion stability of the nanoparticles can be studied by the stability theory of the colloid. The repulsion potential energy and gravitational potential energy between colloidal particles are the key to determining the stability or coagulation of colloids. According to the causes of these two forces and their interactions, the following three mature colloidal stability theories are formed: (1) DLVO Theory; (2) theory of steric stabilization; (3) theory of electrostatic steric stabilization.
