According to the experts, Cs0.32WO3 for preparing window heat insulation film is also known as cesium tungsten bronze, which is a hexagonal tungsten bronze compound consisting of the mixed valence of W6+ and W5+. Wherein, Cs+ ion locates in the space of the WO3 layer. The free electron density of cesium tungsten bronze can be controlled by controlling the amount of Cs+. You know, there are a lot of tungsten bronze compounds, but cesium tungsten bronze shows the most excellent chemical stability because of the adequate ionic size matched with the space size in the WO3 layer.
