Some experts have studied the thermal insulation coating prepared by hydrothermal treatment of Cs0.32WO3 nanoparticles under different acetic acid concentrations. They also used the ratio k as the parameter to evaluate the transparent thermal insulation properties of the coating. Here, k is a ratio of the transmittance maximum value Tmax in the visible light band to the transmittance T1100nm at 1100nm. They found that:

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.

Cs0.32WO3 nanoparticles may be used to prepare a new heat insulating masterbatch --- nano-ceramic color master, which has high thermal insulation performance, high transparency and other excellent properties. And thus such color master may be applied to the production of thermal insulation film and be used to building glass. In this process, some experts observed the effect of ball milling on the grain size and dispersion stability of cesium tungsten bronze nanoparticles.

Cs0.32WO3 nanoparticles, or cesium tungsten bronze nano-functional particles, may be used to nano-ceramic dispersion solution. The obtained dispersion solution is a functional dispersion solution with excellent optical property --- relatively high heat insulation performance and ultraviolet shielding property. Among them, some experts used laser particle size analyzer to observe the distribution of particles of various sizes in the obtained cesium tungsten bronze nano aqueous dispersion and the proportion of the total number of particles.

Some experts used transmission electron microscopy (TEM) to observe the microstructure and particle size distribution of Cs0.32WO3 nanoparticles for thermal insulation dispersion. The sample preparation method is to take a solid content of cesium tungsten bronze nano aqueous phase dispersion and mix with a certain amount of ethanol. After ultrasonic for 5 minutes, take 1-2 drops on a copper mesh covered with 300 mesh carbon film with a plastic dropper, tested after drying naturally.

Experts have shown that Cs0.32WO3 nanoparticles can be used to prepare a new type of thermal insulation dispersion liquid. The prepared dispersion liquid may be used to produce thermal insulation film, including automotive film and architectural film. These films may be applied to many glass applications, making architectural glass and automotive glass turn into a kind of high-tech product with the advantages of high-efficiency heat insulation, UV resistance and radiation protection.

Cs0.32WO3 nanoparticles may be used as heat-insulating functional particles to prepare near infrared shielding material such as heat-insulating film, heat-insulating coating, and thermal insulation dispersion. These materials, which can shield most of the heat in the sun (near-infrared), may be applied to automotive glass and architectural glass. So, why do we need to shield near infrared rays in the sun?

Cs0.32WO3 nanoparticles may be used to prepare infrared thermal insulation nano material such as thermal insulation film and thermal insulation coating, and thus be applied to architectural glass. According to the "National Environmental Pollutant Environmental Health Risk Inventory Physical Volume" published by the Ministry of Environmental Protection, near-infrared rays are harmful to our eyes.

Experts said that the infrared ultraviolet shielding material such as transparent thermal insulation coating prepared by using Cs0.32WO3 nanoparticles as functional particles can have an ultraviolet blocking rate of over 99%, and the near-infrared shielding rate can reach more than 85%.

Cs0.32WO3 particles are cesium tungsten bronze nanoparticles that may be used to prepare thermal insulation coatings and thus be coated on automotive glass to obtain heat insulating window glass. Among them, some experts found that the untreated raw material cesium tungsten bronze powder has a small and uniform grain size. The grains show a regular rod shape, and most of the nanorods have a length of about 50nm.
