Tantalum Metallurgy | SpringerLink
Tantalum metallurgy is the technology to extract tantalum metal from tantalum-bearing material. In 1802, the Swedish chemist A.G. Ekeberg discovered a new element in tantalite and named it tantalum, which was derived from Tantalus, son of Zeus of Greek mythology. A German named H. Rose proved in 1844 that niobic acid and …
