ስለ Terbium
Terbium is a silvery-white, soft, malleable rare earth metal. It is used in green phosphors and has remarkable magnetostrictive properties, changing shape in response to magnetic fields.
ፕሮግራሞች
Green phosphors in displays, magnetostrictive alloys (Terfenol-D for sonar), and fuel cells.
ሐቅ
Terbium-based Terfenol-D changes shape in magnetic fields, making it useful in precision actuators and sonar.
