Cs0.33WO3, or cesium tungsten bronze, is well-known as it is mainly applied for preparing heat insulation coating for applying to the buildings or automobiles to obtain energy efficient glass window with the characteristics of high heat shielding and ultraviolet shielding performance. Well, according to the experts, it is not easy to synthesize Cs0.33WO3 nano particles. Due to its characteristics and structure, cesium tungsten bronze powder produced by most of the preparation methods are micron-sized.

Considering that the particle size of cesium tungsten bronze will affect the near-infrared light absorption and visible light transmission properties of the prepared energy efficient glass window, some experts have adopted a high-temperature carbothermal reduction method and selected appropriate synthesis conditions to prepare cesium tungsten bronze powder with smaller particle size, so as to reduce the ball milling time and reduce the pollution during ball milling, while obtaining nano cesium tungsten bronze powder.
