To produce tungsten powder from ammonium paratungstate, it is usually necessary to first burn tungsten oxide in a weak reducing atmosphere, and then carry out hydrogen reduction to produce tungsten powder. Most of the tungsten powders prepared by this process are very regular polycrystalline, which are the main raw materials for the preparation of tungsten alloy and tungsten carbide.

With high chemical activity and hydrogen reduction rate, violet tungsten oxide has become a significant raw material for preparing tungsten carbide powder. High-quality tungsten carbide powder is usually prepared by carbonization of ultra-fine tungsten powder, which is obtained from violet tungsten oxide.

Violet tungsten oxide with good reducibility and high hydrogen reduction rate is used to prepare ultrafine tungsten powder, so as to obtain high-quality tungsten carbide powder. Carbonization is an extremely important procedure in the preparation process.

Violet tungsten powder with unique needle structure and high chemical activity is an important raw material for the preparation of ultrafine tungsten powder. The preparation process with violet tungsten oxide is usually fast.
