Ammonium metatungstate powder can be used to prepare a transparent heat insulation material, namely cesium tungsten bronze transparent thermal insulation material, which is finally applied to automobile glass to obtain heat insulating window glass. Specifically, the expert proposes a method for heat-insulating and anti-radiation treatment of automobile glass.

Ammonium metatungstate powder may be applied in thermal insulating glass. According to experts, ammonium metatungstate can be used as a raw material to prepare heat-insulating material with a molar ratio of Cs:W:Cl=0.33:1:0.50, and a transparent heat-insulating film may be prepared using the obtained material. Finally, the prepared thin film is applied to architectural glass. Specifically, the processes of preparing the heat-insulating powder and the transparent heat insulating film are as follows:

Ammonium metatungstate powder can be used to prepare cesium tungsten bronze nanopowder, and the obtained functional nanoparticles can be used for producing window heat insulation film. Finally, the transparent film is applied to architectural glass to obtain heat insulation architectural glass. Among them, the experts introduced a preparation method of cesium tungsten bronze nanopowder, including the following steps:

Ammonium metatungstate powder can be used to prepare the raw material required for producing heat insulation coating – cesium tungsten bronze nanoparticles. The finally obtained transparent heat-insulating coating of cesium doped tungsten bronze nano particles can be applied to a transparent substrate such as architectural glass by wet coating.
