Niobium – Wikipedia
Niobium is often found in the minerals pyrochlore and columbite, hence the former name columbium. Its name comes from Greek mythology : Niobe , daughter of Tantalus , the namesake of tantalum . The name reflects the great similarity between the two elements in their physical and chemical properties, which makes them difficult to distinguish.

Niobium and tantalum | U.S. Geological Survey
Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in pipelines, transportation infrastructure, and structural applications. Electronic capacitors are the leading …

Niobium was discovered in 1801 by English scientist Charles Hatchett. It was found in an American ore that had been sent to England more that a century earlier by John Winthrop the Younger, the first governor of the state of Connecticut. Hatchett found the ore, called columbite, in the Hans Sloane collection of the British Museum.
