More details

Terbium (III, IV) oxide (also known as tetraterbium heptaoxide) is relatively stable and easier to be stored. Tb4O7 is one of the main commercial terbium compounds. Terbium Oxide has important role as an activator for green phosphors used in color TV tubes. Meanwhile Terbium Oxide is also used in special lasers and as a dopant in solid-state devices. It is also frequently used as a dopant for crystalline solid-state devices and fuel cell materials. Terbium Oxide is one of the chief commercial Terbium compounds. Produced by heating the metal Oxalate,Terbium Oxide is then used in the preparation of other Terbium compounds.
