Tungsten powder not only has certain requirements for impurity content, but also needs to control the oxygen content within a certain range. The commonly used tungsten powder particle size is generally 2-10 μ m on the Fischer average. Tungsten powder has a polygonal particle shape. In addition, the specific surface area, bulk density, and tap density of tungsten powder also vary within a certain range. The performance of tungsten powder has a direct impact on the production of tungsten materials and the quality of tungsten powder metallurgy products, especially on purity and particle size. Tungsten powder is classified based on purity, particle size, and different applications.
The quality of tungsten powder directly determines the quality and alloy properties of tungsten carbide. The grading of tungsten powder can effectively change the properties of the powder, solve the problem of powder mixing coarse and fine, reduce the difference between small particle size, large particle size and average particle size, and produce coarser and more uniform tungsten carbide powder; Due to the characteristics of tungsten, it is not easily broken. Moderate crushing before classification can separate the agglomerated particles in the powder, which can effectively separate the powder and improve uniformity; Classification requires strict and precise adjustment of system operating parameters, and based on the characteristics of the original powder, it is necessary to find the optimal operating process.
