As violet tungsten oxide has high chemical activity and good air permeability, it is suitable for the production of ultrafine tungsten powder and tungsten carbide powder. At present, a kind of electric heating furnace is applied in the production of violet tungsten oxide.

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.

The preparation of high-quality violet tungsten oxide has attracted more and more attention. In addition to improving the preparation process, upgrading the preparation device can also improve the quality of violet tungsten oxide effectively. Sealed multi-purpose furnace is suitable for the production of high-quality violet tungsten oxide.

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.
