Tantalum Powder Applications

Tantalum metal powder can be used in sputtering targets, alloys, thermal and chemical resistant coating, 3D printing (additive manufacturing), and electrolytic capacitors. There are four types of powders:

  •  Nodular powder from the chemical reduction of tantalum salt or oxide. The resulting powder is aggregated consisting of primary particles and pores. It has a relatively low density and high surface area.
  • EB powder from hydride and de-hydride of electron bean or arc melted ingot. The particle of this powder is typically angular and non-aggregated.
  • Capacitor Grades powder can be used to manufacture high-performance chip or dipping-type tantalum electrolyte capacitors.
  • Spherical powder from plasma inert gas atomization. This generates a spherical shape with a smooth surface that has excellent flow characteristics. The powder is particularly suitable for 3D printing. 

Tantalum Powder Packing

The tantalum powder is carefully handled to prevent damage during storage and transportation.
