Cesium Tungsten Bronze Applied for Energy Efficient Glass

Cesium tungsten bronze for energy efficient glass can be prepared by a solid phase method. For example, some experts prepared cesium tungsten bronze (CsxWO3) nano powder by solid-phase method using cesium hydroxide as the cesium source, tungstic acid as the tungsten source, and tungsten powder as the reducing agent. In the process, experts also studied the effect of annealing temperature on nano powder.

The results show that when the annealing temperature is 500 °C, the crystallinity of the product CsxWO3 is low. While when the temperature is increased to 600 °C, 700 °C, 800 °C, the product has good crystallinity. SEM test results show that when the annealing temperature is 800 °C, the size of the product is large, which is not conducive to subsequent secondary processing. The optical performance test results show that under the condition that the visible light is basically the same (about 60%), CsxWO3 prepared at 600 °C has the best infrared shielding performance, and its infrared shielding value is 90%. In summary, the annealing temperature of 600 °C is the most suitable temperature for experts to prepare cesium tungsten bronze for energy efficient glass in this process.
