Spherical Tantalum Powder

Spherical Tantalum Powder

Spherical Tantalum Powder is a high-purity, fine-grained powder made up of spherical particles of tantalum metal. It is produced using advanced powder metallurgy techniques such as gas atomization and plasma spheroidization, which result in a uniform particle size distribution and a high degree of sphericity.

Spherical Tantalum Powder is widely used in the production of high-performance tantalum alloys and other tantalum-based materials, including capacitors, superalloys, and corrosion-resistant coatings. Its high surface area and uniform particle size make it ideal for applications that require a high level of consistency and control, such as additive manufacturing and thermal spray coating. Additionally, its spherical shape allows for excellent flowability and packing density, which are important factors in powder handling and processing.

Spherical Tantalum Powder Applications

Spherical Tantalum 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. 

Spherical Tantalum Powder Particle Size

5-25μm, 15-45μm, 15-53μm, 45-75μm, 45-105μm, 75-150μm. (Various granularities can be customized according to customer requirements)

Spherical Tantalum Powder characteristics

High purity (99.9%), low oxygen (300ppm), high sphericity (98%), smooth surface, no satellite spheres, uniform particle size distribution, and excellent flow properties (6.0s/50g), And high bulk density (9.5g/cm3) and tap density (10.5g/cm3).
