Nano violet tungsten oxide may be used to prepare transparent thermal insulation nanopowder, which has a wide application in the heat insulation field. And the application of nano grain size violet tungsten oxide in thermal insulation building or automobile has gradually increased with the improvement of people's living standards and environmental awareness. Therefore, nanometer violet tungsten oxide has gradually entered the field of vision of people.
In addition, violet tungsten oxide nanopowder can also be used to prepare tungsten powder. Under the same nitrogen reduction process conditions, tungsten powder prepared from violet tungsten oxide powder is much finer than the tungsten powder prepared from blue tungsten oxide powder or yellow tungsten oxide powder. When the same grade of tungsten powder is produced, yellow tungsten oxide powder or blue tungsten oxide powder is replaced by violet tungsten oxide powder. And the loading amount should be appropriately increased, the pushing speed should be properly accelerated and the nitrogen reduction temperature should be lowered moderately. Therefore, the productivity of the tungsten powder can be remarkably improved, and power and hydrogen consumption can be saved.
