Anders Gustav Ekeberg discovered tantalum in 1802; however, Wollaston declared it was identical with niobium ( then known as columbium ).

Similarly, the British discoverer of " niobium " originally named it " columbium, " in reference to the New World.
13.
Niobium was officially adopted as the name of the element in 1949, but the name columbium remains in current use in metallurgy in the United States.

According to the OED, Columbium got its name because it was discovered in rock from Massachusetts ( Columbia = America ) . talk ) 10 : 00, 28 March 2008 ( UTC)

In 1864 and 1865, a series of scientific findings clarified that niobium and columbium were the same element ( as distinguished from tantalum ), and for a century both names were used interchangeably.
16.
Later Heinrich Rose proved in 1846 that columbium and tantalum were indeed different elements and he renamed columbium " niobium " . ( Niobium and tantalum, being in the same periodic group, are chemically similar .)

I was looking at a new type of photovoltaic device that converts sunlight directly to electricity using a photochemical nano-gate composed of niobium [ columbium ], gold and silver, interchangeably, on one side of the gate.

The Russian chemist R . Harmann proposed that a new element he called " ilmenium " should be present in this mineral, but later, Christian Wilhelm Blomstrand, Galissard de Marignac, and Heinrich Rose found only tantalum and niobium ( columbium ) in it.

I have tried every combination of " solar power energy photovoltaic [ columbium niobium ] gold silver " that I can think of in your search engine, and in Google's search engine with wiki as the first word, and I can not find the article again.
