Tantalum is primarily used in capacitors for microelectronics due to its high heat and electrical conductivity. Niobium can be used as an alternative to tantalum capacitors ("Niobium (Columbium) and Tantalum," 2009), but it is used primarily in alloys for superconducting magnets, rockets, turbines, and medical instruments.
