Stanford Advanced Materials (SAM) offers high-quality spherical tantalum powder known for its high melting point, excellent corrosion resistance, and biocompatibility. Ideal for aerospace, medical implants, 3D printing, and electronics, SAM's tantalum powder ensures superior performance and precision in various advanced applications.
Spherical tantalum powder is generally fabricated by processes such as gas atomization, plasma rotating electrode process, or centrifugal atomization that gives rise to a consistently spherical shape with a particle size distribution accordingly.
The spherical shape enhances flowability; hence, the material is highly appropriate for applications such as 3D printing and powder metallurgy. This shape offers superior packing density and a reduction of porosity in final products.
