Terbium Oxide Nanopowder Tb4O7 Application:

Terbium(III, IV) oxide, occasionally called tetraterbium heptaoxide, has the formula Tb4O7. Tb4O7 is one of the main commercial terbium compounds, and the only such product containing at least some Tb(IV) (terbium in the +4 oxidation state), along with the more stable Tb(III). It is produced by heating the metal oxalate, and it is used in the preparation of other terbium compounds. Terbium forms three other major oxides: Tb2O3, TbO2, and Tb6O11. Main use: Activating agents for fluorescent powders; CeO2-Tb4O7 composites for catalytic automobile exhaust converters; Glass materials with a Faraday Rotation effect for optical and laser-based devices; Magneto-optical glasses; Magneto-optical recording materials.
