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:

 

Ø  Nodular powder from chemical reduction of tantalum salt or oxide. The resulting powder is aggregates consisting of primarily particles and pores. It has relatively low density and high surface area.

Ø  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.

Ø  Capacitor Grades powder can be used to manufacture high performance chip or dipping type tantalum electrolyte capacitors.

Ø  Spherical powder from plasma inert gas atomization. This generates spherical shape with smooth surface which has excellent flow characteristics. The powder is particularly suitable for 3D printing.

 

Heeger Materials offers broad selections of bulk density, particle size range and purity. The purity includes commercially pure, 3N (99.9%), 3N5 (99.95%), 4N (99.99%), and 4N5 (99.995%).
