Tantalum (Ta) Pellets Evaporation Materials

Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. It has a density of 8.58 g/cc, a melting point of 2,468°C, and a vapor pressure of 10-4 Torr at 2,590°C. Haohai Metal offers a full suite of tantalum evaporation pellets at competitive prices. Custom sizes and materials can also be fabricated to meet your requirements.
