Nano grain size cesium tungsten oxide may be used to prepare thermal insulation masterbatch, and thus be applied to produce heat insulating materials such as transparent heat-insulating film for architectural glass. In order to make the obtained masterbatch have good dispersibility in the subsequent products, the raw material cesium tungsten oxide nanopowder, i.e., cesium tungsten bronze nanopowder, must have excellent dispersibility. Therefore, for the agglomerated nanoparticles, it is necessary to carry out related treatment such as surface modification treatment to improve the dispersibility.

Nano grain size cesium tungsten oxide may be used to prepare nano-ceramic color master. The obtained color masterbatch is a functional 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.

Nano grain size cesium tungsten oxide may be used to prepare nano-ceramic dispersion solution. The obtained nano dispersion solution is a blue-black liquid with a dispersed particle size of 40nm or less (D50) and an effective solid content of 30% (adjustable). In addition to being used in the field of building energy conservation and environmental protection with the performance of shielding infrared rays and ultraviolet rays, the nano ceramic dispersion solution of cesium tungsten oxide nanoparticles is also widely used in semiconductors, electronic picture tubes, LEDs, anti-static, radiation protection and other fields.

Nano grain size cesium tungsten oxide, or nano cesium tungsten bronze, may be used to prepare new environmentally-friendly infrared ultraviolet shielding material such as transparent thermal insulation coating. Cesium tungsten bronze transparent heat-insulating coating has the advantages of simple preparation process, low raw material and low equipment input. Therefore, it has better adaptability to the market and higher application value. Therefore, cesium tungsten bronze nanoparticles have very broad application prospects.
