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.
So, the obtained heat insulating glass will have excellent infrared ray shielding rate and high visible light transmittance. And therefore, the cesium tungsten bronze is more and more widely used in the fields of building glass. And it is believed that cesium tungsten bronze is a promising heat insulation material.

The wet coating method may be spin coating, casting, bar coating, blade coating, roller coating, wire bar coating or dip coating. The transparent substrate used may be a glass or a transparent resin layer. The transparent resin layer may be polyethylene terephthalate, polycarbonate, acrylic resin, polypropylene, polyethylene, polystyrene, polyvinyl chloride or the like.
