Characterization of fluidization of tungsten powder and application of fluidization classified tungsten powder in materials for special uses

With a characterization of fluidization of tungsten powder and plotting of related diagrams the paper is intended for a clarification of some principles of fluidization classification of tungsten powders. Application of tungsten powder thus classified indicates that the classification exercises a desirable effect on tungsten powder in particle size composition and therefore contributes much to the improvement of properties of tungsten products and materials.
