History - Tantalum

In 1846 German mineralogist Heinrich Rose separated tantalum and niobium and proved conclusively that Wollaston had made a mistake and that niobium and tantalum were different elements. In 1903, Werner Von Bolton, a German chemist and materials scientist, produced the first pure tantalum samples to be used as filaments for incandescent lighting.2019 DURABOOK Supply Chain Smelter/Refiner List,Tantalum H.C.
