Nano grain size cesium tungsten oxide may be used to prepare nano-ceramic color master. The obtained color masterbatch is a dingal color masterbatch with excellent heat insulating effect, so it can be used for preparing heat insulating materials such as transparent heat insulating film. The thin film is a new type of heat insulating material commonly used in the field of architectural glass. In this regard, experts said that the raw material cesium tungsten nanopowder, that is, cesium tungsten bronze nanoparticles, needs to have good dispersibility, that is, without agglomeration.

So, when it comes to agglomeration, what will affect the agglomeration of nanoparticles? It will be affected by capillary phenomenon. When many particles are close to each other, a large number of capillaries are generated, especially when the powder particles have just been added to the liquid, but the medium has entered the capillary, causing agglomeration of the particles, which is called capillary force.
