Characteristic
Tantalum is a chemical element with the symbol Ta and atomic number 73. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.
Phase at STP：solid
Appearance：gray blue
Melting point：3290 K (3017 °C, 5463 °F)
Boiling point：5731 K (5458 °C, 9856 °F)
Density (near r.t.)：16.69 g/cm3
when liquid (at m.p.)：15 g/cm3
Heat of fusion：36.57 kJ/mol
Heat of vaporization：753 kJ/mol
Molar heat capacity：25.36 J/(mol·K)
Application
It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. Its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems and computers.
