Tantalum is a rare, hard, bluegray, lustrous transition metal that is highly corrosionresistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and .
Tantalum was discovered in Sweden in 1802 by Anders Ekeberg. One year earlier, Charles Hatchett had discovered columbium (now niobium). In 1809 the English chemist William Hyde Wollaston compared its oxide, columbite with a density of g/cm3, to that of tantalum, with a density of g/cm3.

The Extraction and refining of tantalum is done by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures, because of which tantalum and niobium tend to dissolve along with numerous other impurities. With the extract in kerosene, a liquid ion exchange produces highly purified solutions of tantalum and ...
Abstract Studies to better understand the corrosion behavior of niobium in hydrochloric acid solutions have been conducted as part of the Bureau of Mines' effort to conserve the United States' mineral resources. A study of the general corrosion behavior of niobium as a function of acid concentration, time, oxygen, and added ferric ion is reported.
