Nanometer blue tungsten oxide may be applied for producing infrared thermal insulation nano material, such as, heat-insulating films, and heat-insulating sheets, etc. This type of window heat insulation film is a new high-tech product with dings of high heat insulation, high UV resistance, explosion protection, decoration, safety, privacy, energy conservation and environmental protection. It has been widely used in commercial buildings, hotels, and exhibition halls, etc.
The blue tungsten oxide can also be used to prepare tungsten powder. As you may have known, in the 1950s, tungsten acid and yellow tungsten oxide were mostly used in the production of tungsten powder at home and abroad. In the 1960s and 1970s, the United States, France, the Netherlands, the United Kingdom and other countries used blue tungsten oxide, instead of tungstic acid and yellow tungsten oxide, as a raw material for producing tungsten powder. In China, the research on the preparation of tungsten powder from blue tungsten oxide was also started in the 1970s and 1980s.
