Violet tungsten oxide powder may be applied for producing thermal insulation film, and therefore be widely used in the fields of heat insulation such as building glass and automobile glass.
The appearance of violet tungsten oxide is generally light violet or blue violet. The main components and physical properties of violet tungsten oxide are as follows: W18O49 content is more than 97%, oxygen index is less than or equal to 2.72, specific surface is 1.5~3.0m2/g, and bulk density is 1.9~2.3g/cm3.
The impurity element content of the violet tungsten oxide is substantially the same as the impurity element content of the raw material APT.
A large number of research results show that violet tungsten oxide is a raw material suitable for the preparation of ultrafine grained cemented carbide. In other words, violet tungsten oxide has a good development prospect. Violet tungsten oxide has a unique fine needle-like structure. And the chemical activity and hydrogen reduction rate of violet tungsten oxide are larger than that of yellow tungsten oxide and blue tungsten oxide. Therefore, violet tungsten oxide can produce fine and uniform tungsten powder and tungsten carbide powder, faster, better and more economically.
