Terbium Oxide Tb4O7

Product Detail

Brief information Product: Terbium Oxide Purity:99.999%(5N), 99.99%(4N),99.9%(3N) (Tb4O7/REO) Formula: Tb4O7 CAS No.: 12037-01-3 Molecular Weight: 747.69 Density: 7.3 g/cm3 Melting point: 1356°C Appearance: Deep Brown powder Solubility: Insoluble in water, moderately soluble in strong mineral acids Stability: Slightly hygroscopic Multilingual: TerbiumOxid, Oxyde De Terbium, Oxido Del Terbio Application Terbium 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. Terbium Oxide is used for making terbium metal, optical glass, fluorescent materials, magneto-optical storage, magnetic materials, additives for garnet, etc. Terbium oxide powder is pressed and sintered into varistor materials. Used as an activator for fluorescent materials and a dopant for garnet, as an activator for fluorescent powders and an additive for garnet. Packaging：25KG sealed with double PVC bags packed in a steel drum，net weight 50KG. Note:Relative purity, rare earth impurities, non rare earth impurities and other indicators can be customized according to customer requirements Specification
