Tantalum is a rare, heavy refractory metal from the vanadium group, closely related to niobium. Pure tantalum is highly malleable, making it easy to draw into wire or roll into sheets. It forms a protective oxide layer when exposed to air and is resistant to most acids, dissolving only in hydrofluoric acid or molten salts. At high temperatures, it reacts with many non-metals.
Our online shop at Evek GmbH offers tantalum at competitive prices. Reach out for expert advice on your metal requirements.
Tantalum’s primary use is in the electronics industry for producing compact, high-performance capacitors. Thanks to its excellent biocompatibility, it is also used for medical implants and instruments. The chemical industry values tantalum for its resistance to corrosion, and it is added to nickel-based superalloys to improve strength at elevated temperatures.
Main applications of tantalum include:
- Microelectronics (capacitor production)
- Medical field (implants and instruments)
- Chemical industry (heat exchangers, pumps)
- Nickel-based superalloys
Key properties of tantalum:
- Excellent deformability and ductility
- Highly reactive at high temperatures
- Resistant to most acids
- Stable in air due to oxide layer
