Cesium Tungsten Bronze Applied for New Energy-saving Window

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.

A Preparation Method of New Energy-saving Window of Cesium Tungsten Bronze

First, the experts prepared hexagonal Cs0.33WO3 nano particles by solid-phase method, and prepared Cs0.33WO3/SiO2 composite sol by sol-gel method. The sol was coated on a commercial blank glass by a blade coating method to obtain large area all inorganic Cs0.33WO3/SiO2 glass coating. Then, the blank glass and the glass coated with the Cs0.33WO3/SiO2 coating are used to form a glass tank, and the molten paraffin wax is poured into the glass tank to make a Cs0.33WO3-paraffin wax composite window.
