Nano CsxWO3 Powder Applied for Ceramic Microsphere

Nano CsxWO3 powder, or nano particle size cesium tungsten bronze, may be applied for preparing ceramic microsphere. And the raw material for ceramic nanoparticles --- cesium tungsten bronze nanopowder, can be prepared by hydrothermal method. The hydrothermal method uses water as a liquid medium and inorganic salts as a reaction raw material. As you may have known, the preparation of cesium tungsten bronze nano material by this method is a relatively mature process. So, the following is the process.

Preparation of Cesium Tungsten Bronze by Hydrothermal Method

According to the composition of the expected product, some experts use sodium tungstate as the tungsten source and cesium carbonate as the source. First, the raw materials are formulated into a solution according to a certain ratio, and citric acid is used as a stabilizer, and transferred into a water hot kettle together, and hydrothermal reaction is carried out at 190°C/72h. Then, the hydrothermal product was repeatedly washed with ethanol and deionized water, and then dried to at a certain temperature to obtain nano particle size CsxWO3, which is excellent in optical properties.
