Tantalum is a rare, heavy transition metal from the vanadium group, similar to niobium. Pure tantalum is highly malleable and ductile, making it easy to roll into sheets and wires. At elevated temperatures, tantalum reacts with most non-metals, but forms a protective oxide layer in air. It resists most acids, dissolving only in hydrofluoric acid and molten salts.

Tantalum is widely used in electronics for manufacturing compact, high-performance capacitors. Thanks to its biocompatibility, it is also used in medical implants and instruments. Its chemical resistance makes it valuable for the chemical industry, while its ability to strengthen materials at high temperatures makes it a key alloying element in nickel-based superalloys.
Key applications for tantalum include:
- Microelectronics (capacitor manufacturing)
- Medicine (implants and instruments)
- Chemical industry (heat exchangers and pumps)
- Nickel superalloys
Main properties of tantalum:
- Excellent malleability and ductility
- High reactivity at elevated temperatures
- Outstanding resistance to most acids
- Stable in air due to protective oxide layer
