Cesium tungsten bronze nanopowder is an important functional material for preparing balcony thermal insulating glass coating. It is known that both ultraviolet (UV) and infrared (IR) radiation are potentially dangerous. And we are very often exposed to the radiations in many working and living places.

Cesium tungsten bronze is often used to prepare an environmentally friendly sunroom thermal insulating coating without containing poisonous and harmful substances. According to the experts, cesium tungsten bronze is a type of tungsten bronze structure material MxWO3 with the formula of CsxWO3. And the CsxWO3 nanopowder possesses mixed valence state of tungsten (W5+ and W6+). Their crystal structure changes with their different x values.

Cesium tungsten bronze for preparing car thermal insulating glass coating is mainly cesium tungsten bronze nanopowder, such as Cs0.33WO3 nanopowder. It is reported that the Cs0.33WO3 is a type of the mixed valence state tungsten based homogeneous nanomaterials that possess excellent infrared (IR) light shielding property, implying its great potential applications on heat ray shielding and energy saving effect in summer season.

Cesium tungsten bronze, such as Cs0.32WO3 nanopowder, has high near-infrared absorption performance and high visible light transmission, so it is often prepared into building glass thermal insulating coating. And the prepared environmentally-friendly heat insulation coating has good application prospects in exhibition halls, hotels, schools, hospitals, villas, office buildings, sun rooms and other buildings.
