Cs doped tungsten oxide may be applied for producing transparent thermal insulation material, which is more and more widely used in building glass. Therefore, experts are also paid much attention to such material. They proposed a preparation method of cesium doped tungsten oxide nano powder, the specific process is as follows: Adopt sodium tungstate as raw material to prepare a certain concentration of sodium tungstate solution. Prepare the tungstic acid sol by cation resin exchange. And then an appropriate amount…
