CAS 7440-25-7: Tantalum

Description: Tantalum is a rare, hard, blue-gray metal that is highly resistant to corrosion and has a high melting point, making it valuable in various industrial applications. It belongs to group 5 of the periodic table and is classified as a transition metal. Tantalum is known for its excellent conductivity and is often used in the production of capacitors and high-power resistors, particularly in the electronics industry. Its resistance to chemical attack allows it to be used in environments that would corrode other metals, such as in chemical processing equipment and surgical implants. Tantalum is also biocompatible, which makes it suitable for medical applications. The metal is typically extracted from tantalum-containing minerals, such as columbite and tantalite, through complex separation processes. Due to its scarcity and the geopolitical issues surrounding its mining, tantalum is considered a critical material in technology and defense sectors. Overall, tantalum's unique properties make it an essential element in modern technology and materials science.
