Terbium Metal
Terbium (chemical symbol: Tb, CAS 7440-27-9) is a rare earth metal from the lanthanide series, featuring a molar mass of 158.9 g/mol. It is a silvery metallic solid with a melting point of 1,359 °C and a boiling point of 3,230 °C, and a density of 8.23 g/cm³ at 25 °C. The metal is stable, non-combustible, and relatively resistant to oxidation under normal handling conditions.
Due to its unique electronic and magnetic characteristics, terbium plays an essential role in modern technology. It is widely used in phosphors for fluorescent and LED lighting, high-performance alloys, magneto-optical devices, and solid oxide fuel cells (SOFCs). These applications leverage terbium’s ability to enhance luminescence efficiency, magnetic responsiveness, and energy performance.
