W ithin a short time after the discovery of columbium by Mr. Hatchett in 1801, a metallic substance was also discovered in Sweden by M. EKEBERG, differing from every metal then known to him ; and accordingly he described the properties by which it might be distinguished from those which it most nearly resembled. But although the Swedish metal has retained the name of Tantalum given to it by M .Ekeberg, a reasonable degree of doubt has been entertained by chemists, whether these two authors had… 
Four brilliant students of Henri Sainte-Claire Deville 2. Louis Joseph Troost
Louis Joseph Troost (1825-1911) carried on a large number of researches, alone or with Deville, Hautefeuille, and other colleagues, on the isolation of lithium, determination of its atomic mass, and

Separation of tantalum and niobium with solvent extraction
Separation of tantalum and niobium with solvent extraction. Niobium (Nb) and tantalum (Ta) have similar chemical and physical properties, which is why they are difficult to separate. They are found
Tantalum in the environment
World War II, tantalum, and the evolution of modern cranioplasty technique.
The experiences of wartime neurosurgeons with tantalum cranioplasty played a pivotal role in the evolution of modern crANIoplasty techniques and ultimately led to a heightened understanding of the necessary attributes of an ideal synthetic cranioprostheses material.

The first article in this series [1] covered the early history of electrolytic capacitors, from their invention around 1880 to the invention of the modern Al electrolytic capacitor structure in 1925.
Sustainability evaluation of essential critical raw materials: cobalt, niobium, tungsten and rare earth elements
The criticality of raw materials has become an important issue in recent years. As the supply of certain raw materials is essential for technologically-advanced economies, the European Commission and
