Violet tungsten oxide is an important raw material for the preparation of tungsten powder. During the preparation process, the fluidity of violet tungsten oxide directly determines the feeding speed of rotary furnace. Only when violet tungsten oxide with high fluidity is applied, can high-quality tungsten powder be prepared.

Copper modified violet tungsten oxide is a kind of photocatalyst with good photocatalytic performance. As for its preparation, solution method is applied. This kind of preparation method is not only simple, but is suitable for large-scale production.

With high chemical activity and unique needle structure, violet tungsten oxide is an ideal raw material for preparing ultrafine tungsten powder. When applied in the production of tungsten powder, it can effectively improve the quality and performance of tungsten powder products.

Violet tungsten oxide is a kind of photocatalyst with special surface structure and oxygen defect structure. In addition, copper can improve the response of the photocatalyst in the visible region. Therefore, copper modified violet tungsten oxide has broad application prospects in the field of photocatalyst.
