Nano cesium tungsten bronze for glass curtain wall heat insulating coating was prepared by a solid phase reaction method (phase/phase heating reduction method) --- a method of high-temperature solid phase reduction in the early days. As the solid phase reaction method is commonly used, there are many reports in the literature.

Nano cesium tungsten bronze is a new type of functional material that can achieve sunshade, heat insulation and energy-saving effects. So, it is often used to study and prepare office building heat insulating glass coating. At present, most of the office buildings adopt glass curtain wall to highlight the fashion style. However, while bringing high transparency and beautiful appearance, there are also problems such as poor heat insulation, radiation and serious light pollution, which make the white-collar workers in the building miserable.

Nano cesium tungsten bronze is a new type of functional nano powder that is used to prepare sun room heat insulating glass coating. The prepared coating is a kind of smart material that combines nano technology and nano material with excellent heat insulating, ultraviolet shielding and explosion-proof performance, and thus it has wide application prospects.

Nano cesium tungsten bronze is applied to prepare study heat insulating glass coating for optimum performance such as high shielding performance of near-infrared rays and high transparency. Therefore, such smart coating is more and more widely applied to building glasses. Among them, cesium tungsten bronze is a kind of tungsten bronze material with hexagonal structure. This is because the radius of Cs+ ion is slightly larger than the size of the hexagonal tungsten bronze structure tunnel.
