Terbium Oxide Powder (Tb4O7), CAS 12037-01-3
Terbium oxide powder (Tb4O7) is a light green powder that is commonly used as a raw material for the production of other terbium compounds, such as terbium metal, terbium fluoride, and terbium nitrate.
Terbium oxide is insoluble in water, but soluble in acids. It has a high melting point of 2,350 °C and a high thermal conductivity, making it useful in high-temperature applications. It is also used as a green phosphor in television screens, as a dopant in the production of solid-state lasers, and as a magneto-optical recording material.
Terbium oxide powder should be stored in a cool, dry place, away from heat sources and incompatible materials. Proper protective equipment, such as gloves and safety goggles, should be worn when handling this material.

Applications
Terbium Oxide, also called Terbia, has an 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.
