AEM provides various Terbium products, including:
Element category: Lanthanide
Terbium is a silvery, malleable, ductile, rare earth metal. It is a member of the lanthanide group of the periodic table.
Swedish chemist Carl Gustaf Mosander discovered terbium in 1843. Terbium is a silvery-gray, malleable, soft, and ductile, rare earth element that can be cut by a knife. Terbium is relatively stable in the air. Terbium can be used as a dopant in calcium fluoride, calcium tungstate, and strontium molybdate. As a component of Terfenol-D, terbium is used in actuators, naval sonar systems, sensors, and other devices.
Terbium is rare and expensive, so it has few commercial uses. It is mainly used to dope calcium fluoride, calcium tungstate, and strontium molybdate, materials that are used in solid-state devices. When together with zirconium dioxide (ZrO2), terbium is used as a crystal stabilizer in fuel cells that operate at high temperatures. It is also used in lasers, semiconductor devices, and phosphorous in color television tubes.
