Ammonium metatungstate powder and cesium carbonate powder can be used as the main raw materials for preparing cesium tungsten bronze. The obtained powder is cesium tungsten bronze nano powder, which can be used to produce a variety of new type of infrared thermal insulation nano material such as transparent thermal insulation film, thermal insulation coating and thermal insulation dispersion for architectural glass.

Ammonium metatungstate powder can be used to prepare tungsten oxide nano aqueous solution, and thus be applied to the production of transparent thermal insulation material, which is energy-saving and environmentally friendly of high heat insulation performance.

Ammonium metatungstate powder can be used together with cesium hydroxide to prepare cesium tungsten bronze nanoparticles. And the obtained cesium tungsten bronze functional nanoparticles can be used as a raw material for producing transparent infrared ultraviolet shielding material such as transparent thermal insulation film and thermal insulation coating for architectural glasses. In this regard, experts have proposed a preparation method that can shorten the reaction time of cesium tungsten bronze.

Ammonium metatungstate powder, or AMT, can be used to produce tungsten oxide. AMT is called transparent thermal insulation nanopowder as the tungsten oxide heat-insulating material prepared using it as raw material is transparent.
