Nano tungsten powder and ultrafine tungsten powder are prepared by variable current laser ion beam gas phase method, with uniform particles, high activity and large specific surface area. After passivation treatment, the oxygen content of the powder can be controlled below 1%. Nano-tungsten powder is used in aerospace alloys, electronic packaging alloys, electrode materials, microelectronic films, sintering aids, protective coatings, gas sensor electrodes, etc. It is used to manufacture high-performance tungsten products and to process and manufacture nano-Wu wires. The excellent properties of nano-Wu wires are used to produce high-performance ultra-fine nanocrystalline alloys and high-density alloys. It has become an indispensable functional material in many high-tech fields. . The cemented carbide produced by nano tungsten powder has extremely high hardness and is the leading product of tungsten materials.

Tungsten powder is one of the important raw materials for preparing powdered tungsten and its alloy products.
