Nano cesium doped tungsten oxide may be applied for preparing thermal insulation paper - a new type of environmentally friendly transparent heat insulation film. As you may have known, the chemical formula of cesium doped tungsten oxide is CsxWO3 (0<x<0.33). According to its chemical formula, the valence state of tungsten in the Cs doped tungsten oxide system is in a reduced state, and with the increase of cesium ions, the tungsten ions of low valence state increase, which indicates that a certain reducing atmosphere is required for the synthesis of cesium doped tungsten oxide powder.
