Tungsten oxide nanopowder, which may be applied for the production of thermal insulation dispersion liquid, may be prepared by chemical precipitation method – a type of liquid phase method. Preparation of Tungsten Oxide by Chemical Precipitation Method The SnO2-WO3 powder can be synthesized by chemical precipitation method. Specific processes are shown as below. The sodium tungstate and the tin tungstate solution are uniformly mixed, and then the solution is slowly dropped into boiling dilute sulfuric acid, and the obtained precipitate…
