Terbium is a soft, malleable, ductile, silver-grey metal member of the lanthanide group of the periodic table. It is reasonably stable in air, but it is slowly oxidised and it reacts with cold water.

Terbium is rare and expensive, so it has few commercial uses. Some minor uses are in lasers, semiconductor devices, and phosphorous in colour television tubes. It is also used in solid-state devices, as stabilizer of fuel cells which operate at high temperature.
