Cesium tungsten bronze for preparing office thermal insulating film is a type of MxWO3 tungsten bronze with a chemical formula of CsxWO3. What are the structures of MxWO3 tungsten bronze? Generally, the structures of MxWO3 type tungsten bronze are cubic structure (PTB), tetragonal structure (TTB), symbiotic structure (ITB) and hexagonal structure (HTB).

In the hexagonal structure, since the structure tunnel is large in size, it is possible to incorporate larger radius ions to form tungsten bronze such as KxWO3, RbxWO3, and CsxWO3. It is reported in the literature that the concentration x of the most incorporated ions in the hexagonal structure is 1/3, generally less than 1/3. In addition, MxWO3 type tungsten bronze has a wide variety of properties due to its variable structure, the type and concentration of M ions incorporated. So, the cesium tungsten bronze often has near-infrared rays shielding performance with hexagonal structure.
