Element 41 was discovered in England in 1801 by Charles Hatchett while analyzing a sample of rock (columbite) sent to the British Museum from the United States. Until the discovery of pyrochlore deposits at the beginning of the 1950s, almost simultaneously in Canada (Oka) and in Brazil (Araxá), the use of niobium was limited. With the primary production of niobium, it became plentiful and an important element in the development of today's engineering and other materials.
