  • Tantalum - Wikipedia

    Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.

  • Tantalum and niobium - Critical Metals Handbook - Wiley ...

    2013-12-27  Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum minerals are oxides, rather than silicates, sulfides or phosphates.

  • NIOBIUM AND TANTALUM - PROMETIA

    Tantalum (Ta) is a dense, tough and ductile element with very high melting point of 3017ºC. It is also highly corrosion-resistant to most acids below 150ºC and, in most cases, chemically inert. It has good thermal and electrical conducting properties and is easy to machine.

  • Tantalum VS Niobium – Magic Metal Tantalum

    2019-06-27  Tantalum and niobium belong to one family in the periodic table. Due to their similar physical and chemical properties, as well as growing together in the same ore body, they are known as the twin of metals. Tantalum and niobium were discovered in 1801 and 1802 by Charles Hatchett, a British chemist, and Ekberg, a Swedish chemist.
