Nano cesium tungstate powder, with molecular formula of Cs2WO4, is a kind of infrared thermal insulation nano material that is applied on the architectural glass in the form of transparent heat insulation coating. Preparation of Nano Cesium Tungstate Powder Step one: Sodium tungstate and cesium carbonate are dissolved in citric acid solution and methanol solvent, after stirring, the reaction is performed at 180-200°C for 2~3 hours. Then, the mixed liquor of tungsten and cesium is obtained. n(CS)/n(W) = 0.33:1. Step…
