Cesium tungsten oxide nano powder may be applied for producing a type of transparent thermal insulation paper – thermal insulation film. First, we should know how the nano cesium tungsten oxide powder is prepared? Some experts used sodium tungstate and barium carbonate as raw materials, D-malic acid as reducing agent, raw material Cs/W ratio of 0.5, and hydrothermal reaction at 175°C for 72h, successfully synthesized rod-shaped Cs0.32WO3 nanoparticles with excellent near-infrared absorption properties. And they found that the improvement of…
