Niobium Facts 3: discovery of Niobium

Let’s talk about the discovery of Niobium. In 1734, John Winthrop discovered an ore in Massachusetts. He decided to send the ore to England. For many years, the ore was only kept in British Museum Collections. Charles Hatchett analyzed the ore in 1801.  When he analyzed the ore, he found a new element. He named it columbium. It was named after the poetic name of America, Columbia.

Niobium Facts 4: William Hyde Wollaston

The discovery of Niobium was not easy. William Hyde Wollaston made a comparison of columbite and tantalite in 1809. This English chemist found out that columbium was actually the element of tantalum. Both are not easy to isolate and often found together.

Niobium Facts 5: Heinrich Rose

Heinrich Rose made another experiment using the samples of tantalite and columbite in 1844. The experiment generated two kinds of acids. He called niobic acid and pelopic acid. But then he called it niobium.

Niobium Facts 6: Jean Charles Galissard de Marignac

Jean Charles Galissard de Marignac was a Swiss chemist who isolated metallic niobium 20 years after the experiment of Rose in 1844. He got niobium by heating chloride in a hydrogen atmosphere.
