Cesium tungsten bronze is a new type of environmentally friendly heat-insulating dingal particles that can be used to prepare exhibition hall thermal insulating glass coating. In recent years, environmentally-friendly heat insulation materials such as environmentally-friendly thermal insulation coating have become popular. Because, we are beginning to realize that we only have one planet, and we need to guard the only planet we live on.

Therefore, the preparation method of cesium tungsten bronze, especially the preparation method conforming to the energy conservation and emission reduction policy, has attracted more and more attention. For example, some experts use sodium tungstate and cesium carbonate as raw materials to synthesize CsxWO3 powder for glass heat-insulation coatings with controlled morphology and structure. Among them, the synthesis process does not require H2 reduction at high temperature. Instead, it is reacted for 1-3 d at 180-200 °C by adding a citric acid reducing agent. The method adopts low-cost, mild and easy-to-operate raw materials such as sodium tungstate and cesium carbonate, which can reduce production cost. And it is synthesized at a low temperature, conforming to energy saving and emission reduction policies, so that it is suitable for large-scale industrial production.
