Tantalum is a rare, hard blue-grey metal. It is highly resistant to corrosion. It was discovered in Sweden in 1802 by Anders Ekeberg. It was isolated in 1820 by J.J. Berzelius
Tantalum is used primarily for the production of capacitors found in consumer electronics products such as cell phones, DVD players, computers, and games. Tantalum is used for the electrode part of the capacitor where they achieve good performances with higher frequencies.
