Tantalum (Ta) is a transition metal that was discovered in 1820. It is greyish blue in color with a metallic shine and is resistant to corrosion and acids. Tantalum is a good electrical and heat conductor with a high fusion point. It is commonly used in the fabrication of electrolytic condensers and is an essential component of compact electronics. Global tantalum reserves are primarily located in Africa, and extracting it causes significant exploitation and dangerous working conditions for miners.
