Tungsten oxide nanopowder is a kind of transparent thermal insulation nanopowder, which may be applied to the glasses of buildings or vehicles in the form of heat-insulating film. And it plays the role of heat insulation and energy saving in this field.
Thermal insulation glass of tungsten oxide is better than coated glass of other metals, non-metals and oxide films thereof as these glasses have a certain reflection effect on solar heat, which will seriously affect the transmittance of visible light and bring "light pollution". As you may have known, light pollution is blamed for compromising health, disrupting ecosystems and spoiling aesthetic environments. And therefore, these types of glasses cannot be widely used. While glasses of tungsten oxide has good visible light transmittance. And it is anti-glare. In other words, glasses of tungsten oxide prevent light pollution.
Tungsten oxide is also a photocatalyst. And what should be noted is that the photocatalyst of tungsten is not limited to tungsten oxide. In addition, there are various tungstate photocatalysts such as PbWO4, CdWO4, Ag2WO4, Bi2WO6 and the like.
