탄탈럼은 전자 커패시터와 수술용 임플란트에 쓰이는 단단하고 내식성이 큰 금속이다. 생체 적합성이 매우 높다.

탄탈럼 개요

Hard, dense, and highly resistant to corrosion, tantalum (Ta) withstands attack by most acids, a durability that defines its applications. Element 73 lies in group 5 of period 6 in the d-block, with an atomic mass of 180.95, the electron configuration [Xe] 4f¹⁴ 5d³ 6s², and a Pauling electronegativity of 1.5. Its ability to form a thin, stable insulating oxide makes it the material of choice for the compact capacitors found in phones, computers, and other electronics. Because the metal is inert and well tolerated by the body, it is also used in surgical implants and instruments. Tantalum is solid at standard temperature and pressure.
