Violet tungsten oxide with unique needle structure and high chemical activity has broad application prospects in the preparation of tungsten powder and tungsten carbide. Generally, it is obtained by calcining ammonium paratungstate in a calciner.

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.

As a kind of multi-functional material, violet tungsten oxide has high application value in many fields such as fuel cells and thermal insulation materials. It is generally prepared by calcining ammonium paratungstate in a rotary furnace. The selection of rotary furnace is the key to high-quality violet tungsten oxide.

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.
