  • Tantalum and Niobium Industry Annual Report 2020

    2021-3-23  1. Definition, Type, Distribution, Application 1.1 Definition of Tantalum and Niobium Tantalum is a tough, ductile metal with the symbol of Ta and Mohs hardness of 6.5. When exposed to air, tantalum forms a very dense oxide layer. Its melting point is 2,996°C, which is only lower than that of tungsten, rhenium and osmium. Tantalum with good ductility property can be drawn into thin foils.
