Cesium tungstate, or cesium tungsten bronze, or cesium tungsten oxide, with the formula of Cs0.33WO3, is mainly used for preparing transparent glass coating, which shields heat with high near-infrared absorption performance. According to the experts, the Cs0.33WO3 heat insulation coating can effectively depress solar heat gain and air-conditioning energy consumption of buildings, because of its highly selective near infrared (NIR) absorbing ability.

Cesium tungstate for preparing glass curtain wall heat insulation coating is also known as cesium tungsten oxide with formula of Cs0.33WO3. In addition to producing transparent heat insulation coating, it can also be used to prepare transparent heat insulation film. The film can be a PVB heat insulation clip film. And the film can be a building window film or an auto film, for reducing temperature, saving energy, and protecting the environment.

Cesium tungstate for greenhouse heat insulation coating is also known as cesium tungsten oxide with formula of Cs0.33WO3, particle size of 80-100nm, and purity of 99.9%. It is dark blue in color. Cs0.33WO3 nano particles are often prepared into dispersion for production of highly transparent heat insulation coating.

Cesium tungstate for producing car heat insulation film is known as a functional material, an energy saving material, a near-infrared (NIR) shielding material, or a heat shielding material. It is the absorption of NIR that makes the cesium tungstate (Cs0.33WO3) nanoparticles apply to produce car heat insulation film.
