History of Columbium / Niobium. Niobium, discovered in 1801 by C. Hatchett, an English Chemist in an ore called columbite, is a metal that is closely related to tantalum. It was originally thought that the material was chromium but upon analysis it was determined it was not chromium but an oxide of an unknown element.

Niobium. Due to the great chemical similarity of niobium and tantalum, the establishment of the individual identities of the two elements was very difficult. Niobium was first discovered (1801) in an ore sample from Connecticut by the English chemist Charles Hatchett, who called the element columbium in honour of the country of its origin,...

Other, less common oxides of niobium and tantalum include tapiolite, ixiolite, and minerals of the perovskite group. Niobium and tantalum also substitute for major ions in some common oxide groups such as cassiterite, rutile, and ilmenite. Contents of niobium and tantalum in these minerals are rarely high enough to make them of economic interest.

Columbium and tantalum ordinarily occur in nature as isomorphous mixtures of the pentoxides of the metals and it is extremely exceptional to find one without a considerable proportion of the other. When the tantalum pentoxide content is higher than the columbium pentoxide, the ore is called tantalite; similarly when the columbium pentoxide content is higher, the ore is called columbite.
