Charles Hatchett FRS FRSE (2 January 1765 – 10 March 1847 [1]) was an English mineralogist and analytical chemist who discovered the element niobium, for which he proposed the name "columbium". [2] Hatchett was elected a Fellow of the Linnaean Society in 1795, [3] and of the Royal Society in 1797.

The mineral columbite The element niobium. In 1846, Rose rediscovered the chemical element niobium, proving conclusively that it was different from tantalum. This confirmed that Charles Hatchett had discovered niobium in 1801 in columbite ore. Hatchett had named the new element "columbium", from the ore in which niobium and tantalum coexist.
Perey discovered it as a decay product of 227 Ac. [177] Francium was the last element to be discovered in nature, rather than synthesized in the lab, although four of the "synthetic" elements that were discovered later (plutonium, neptunium, astatine, and promethium) were eventually found in trace amounts in nature as well.

Niobium becomes a superconductor at cryogenic temperatures. At atmospheric pressure, it has the highest critical temperature of the elemental superconductors at 9.2 K. [66] Niobium has the greatest magnetic penetration depth of any element. [66] In addition, it is one of the three elemental Type II superconductors, along with vanadium and ...

Niobium is similar to tantalum, and the two are difficult to distinguish. This similarity has lead to confusion over the years during process of its recognition and naming. Niobium was first discovered in columbite in 1801, by the English chemist Charles Hatchett who initially named it columbium; that mineral has since been renamed niobite.
