Tantalum, represented by the chemical symbol Ta, is a steel-gray metal belonging to the VB family in the periodic table with atomic number 73 and atomic weight 180.9479. It has a body-centered cubic crystal structure and a common valence of +5. Tantalum's hardness is relatively low and is influenced by its oxygen content. Ordinary pure tantalum, when annealed, has a Vickers hardness of only 140 HV. Its melting point is extraordinarily high at 2995°C, ranking fifth among elemental substances, following carbon, tungsten, rhenium, and osmium. Tantalum is extremely malleable, allowing it to be drawn into thin wires. It has a remarkably small coefficient of thermal expansion, expanding only 6.6 parts per million per degree Celsius. Additionally, its toughness surpasses that of copper.
Predominantly found in tantalite, tantalum often coexists with niobium. It has moderate hardness and excellent ductility, allowing it to be formed into thin foils and fine wires. Its chemical properties are highly stable, and it exhibits exceptional resistance to corrosion, largely due to the formation of a stable tantalum pentoxide (Ta2O5) protective film on its surface. This unique resistance makes it ideal for various applications such as manufacturing evaporators, electrodes for electronic tubes, rectifiers, and electrolytic capacitors. In the medical field, tantalum is used to fabricate sheets or threads for repairing damaged tissue.
Tantalum's exceptional properties make it highly versatile with a broad range of applications.
Tantalum serves as an effective substitute for stainless steel in producing various inorganic acids.
In industries such as chemical, electronic, and electrical,
tantalum can take on roles previously fulfilled by precious metals like platinum.
Tantalum is widely used in the manufacture of capacitors, especially for military equipment.
Remarkably, half of the global tantalum production is dedicated to manufacturing tantalum capacitors.
