Some experts have proposed a method for synthesizing nano cesium tungsten bronze for preparing glass curtain wall thermal insulating glass coating. The experts used tungstic acid as a tungsten source, and water or ethanol as a solvent. And the hydrothermal or solvothermal reaction was performed at a high temperature of 180-220 °C for 3 days, and finally the nanopowder with a phase composition of Cs0.32WO3 was obtained. Wherein, the molar ratio of W: Cs is 1: (0.01-0.35). However, due to the long hydrothermal/solvothermal synthesis time, low yield, high cost, and difficulty in achieving industrial application involving high temperature and pressure, the industrial preparation technology of cesium tungsten bronze nanomaterials has been a bottleneck restricting its wide application.
