As we all know, there are many factors that affect the performance of tungsten powder

wallpapers News 2021-02-05
As we all know, there are many factors that affect the performance of tungsten powder. But the main factors are nothing more than the production process of tungsten powder, the characteristics and characteristics of the raw materials used, etc. In general, there are many studies on the effect of the reduction process on the performance of tungsten powder, including reduction temperature, propulsion speed, shipload and method, and reducing the atmosphere.
 
However, in the process of production and research, researchers found that the properties of different tungsten oxide raw materials also have a greater impact on the properties of tungsten powder. Next, let us look at the influence of tungsten oxide raw materials (yellow tungsten oxide WO3, blue tungsten oxide WO2.98, purple tungsten oxide WO2.72 and tungsten dioxide WO2) on the properties of tungsten powder.
Purple tungsten oxide
1. The characteristics of different tungsten oxide raw materials directly determine the size and composition of tungsten powder, its physical properties, such as compatibility and formability, the content of impurity elements, and the morphology and structure of tungsten powder. In actual production, raw materials should be selected according to the requirements of tungsten powder when selecting raw materials, which is conducive to ensuring product quality and achieving good economic benefits.
 
2. The oxygen content in tungsten oxide raw materials is positively correlated with the Fss of tungsten powder. Purple tungsten oxide with lower oxygen content is used as a raw material for the production of ultrafine tungsten powder, and yellow tungsten oxide with higher oxygen content is used to produce coarser tungsten powder. Tungsten and blue tungsten oxide are used as raw materials.

3. The tighter the particle structure of the tungsten oxide raw material, the slower the reduction rate, the coarser the tungsten powder produced, and the wider the particle size distribution. In order to produce high-concentration tungsten powder, it is recommended to choose oxide raw materials with a single-phase composition, loose internal structure and uniform particles.
 
4. For the production of tungsten products and tungsten products with special performance requirements, it is best to choose specially treated tungsten oxide or purple tungsten oxide as raw materials.
 
5. Pure tungsten powder can be made into processing materials, such as metal wires, rods, tubes, plates and products with certain shapes. In addition, tungsten powder mixed with other metal powders can also be made into various tungsten alloys, such as tungsten-molybdenum alloy, tungsten RH alloy, tungsten copper alloy and high-density tungsten alloy.
