Terbium is a chemical element with symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. Terbium is used in solid-state devices, as a crystal stabilizer in fuel cells, and in specialized alloys.
Description: Terbium is a rare earth element discovered in 1843 by Swedish chemist Carl Gustaf Mosander. It is found in minerals such as cerite, gadolinite, and monazite. Terbium is used in various high-tech applications, including as a dopant in solid-state devices, in phosphors for color TV tubes and fluorescent lamps, and in magnetostrictive alloys like Terfenol-D. It also has applications in fuel cells as a crystal stabilizer. Terbium is not traded as a standalone financial asset but is part of the rare earth metals market, which is influenced by supply from China and demand from electronics and green energy sectors.
