Nanometer violet tungsten oxide may be applied for producing thermal insulation coating, and therefore be used as a raw material for preparing thermal insulation film. With the improvement of people's living standards and the awareness of environmental protection, people are pursuing more environmentally friendly thermal insulation films. Therefore, thermal insulation film of violet tungsten oxide with excellent heat insulation and environmental protection properties is sought-after.
The violet tungsten oxide has unique needle-like crystal shape with a large gap therebetween, and thus the polymer of violet tungsten oxide is loose. Violet tungsten oxide can be prepared by APT mild reduction method. When hydrogen reduction is carried out, this large gap facilitates the infiltration of hydrogen and the escape of water vapor, so that the tungsten powder is formed at high speed with a large number of crystal nuclei and fine particle size. Tests have shown that among tungsten powders prepared under different hydrogen reduction conditions with different tungsten oxides, the tungsten powder prepared by using violet tungsten oxide as raw material is the finest.
