Tetraterbium heptaoxide Usage And Synthesis
- Chemical Propertiesdark brown powder(s), or sintered pieces 3–12mm; slightly hygroscopic; absorbs atmospheric CO2; used as an evaporation material of 99.9% purity; possibly reactive to radio frequencies [HAW93] [CER91]
- UsesTerbium Oxide, also called Terbia, 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.
- Purification MethodsDissolve it in acid (e.g. perchloric acid), precipitate it as its oxalate and ignite the oxalate at 650o.
