Cesium tungsten bronze for preparing dining room thermal insulating film is a type of tungsten bronze material, which can be prepared by a conventional preparation method such as a solvent chemical reduction method. So, what is the solvent chemical reduction method?

Solvent chemical reduction is a process in which a raw material is immersed in an acidic solution and then subjected to a redox reaction in a specific reactor such as an autoclave or a closed vessel. Generally, there are reducing substances such as Zn, Pb, Sn, amalgam, an organic and inorganic reducing solvent in the reaction solvent. Among them, the hydrothermal method is an important method in the solvent chemical reduction method. However, the early hydrothermal reaction temperature is high, and the reaction vessel is reacted in a closed vessel of a gold tube with high cost. Therefore, at present, the low temperature hydrothermal method is commonly used. In fact, there are two conventional methods for preparing tungsten bronze, namely high temperature solid phase reduction and electrochemical reduction. Certainly, with the development of science and technology, many kinds of MxWO3 preparation methods have been developed.
