Cesium tungsten bronze is a functional material with excellent near-infrared shielding properties that can be used to design and produce a new type of energy-saving window. For example, some experts have composited cesium tungsten bronze (such as Cs0.33WO3) of heat shielding function with phase change of materials (such as paraffin wax) to design a new type of energy-saving composite window.

Cesium tungsten bronze is widely used to prepare building energy saving coating because it can effectively suppress the solar heat gain of buildings and the energy consumption of air conditioning. And it is due to the high visible light transmittance and excellent near-infrared light (NIR) shielding performance of the nano powder of cesium tungsten bronze (CsxWO3, such as Cs0.33WO3). So, do you know why Cs0.33WO3 can transmit visible light? And why can Cs0.33WO3 shield near-infrared light?

Cesium tungsten bronze is often used to produce solar film as a near-infrared absorption additive to reduce the amount of solar energy (UV radiation and infrared heat) transmitted through a film by increasing the solar absorption of the glass, improving the comfort in homes and automobiles without sacrificing visibility.

As a heat shielding material, cesium tungsten bronze is known to all. Well, do you know potassium cesium tungsten bronze? It is also a heat-shielding material. Here is a method for the preparation of potassium cesium tungsten bronze particles.
