Tantalum (Ta)
Tantalum (Ta)
Tantalum is a refractory metal, falling between tungsten and molybdenum in terms of melting point (5425 F). Tantalum's corrosion resistance is excellent in a wide range of severe environments. The metal develops an oxide film on exposure, which acts as a barrier to further corrosion. The corrosion resistance of tantalum is often compared to that of glass.
