Importância dos pós esféricos

Spherical powders are advanced materials characterized by particles with a spherical shape, offering a range of benefits compared to irregular powders, particularly in the manufacturing sector.


  • Improved Flow and Density: They enhance flowability and packing density, leading to more efficient processing.
  • Consistência: Spherical particles provide uniform size distribution and a smoother finish on final products.
  • Versatilidade: These powders are suitable for various applications including additive manufacturing and powder metallurgy​1​.

Production Techniques

  • Atomização de gás: Utilizes a high-pressure gas jet to form droplets that solidify into powder.
  • Atomização por plasma: Involves melting metal with a plasma torch, then atomizing it into spheres.
  • Electrode Induction Melting: Melts a metal bar that is then formed into droplets via centrifugal forces.
  • Métodos químicos: Produces particles through chemical precipitation from metal salts​1​.


Spherical powders are integral in sectors such as:

  • Additive manufacturing for 3D printing metals
  • Powder metallurgy for creating sintered parts
  • Metal injection molding for complex components
  • Thermal spraying for coatings
  • Electronics for conductive pastes​1​.


Parameters like particle size, shape, and material type are critical. Customization is often available to meet specific application requirements​1​.


Despite their advantages, spherical powders face challenges such as higher production costs and the need for advanced handling to maintain quality​1​.
