Europium Oxide Eu2O3

Product Detail

Brief information Product: Europium Oxide Formula: Eu2O3 CAS No.: 1308-96-9 Purity:99.999%(5N), 99.99%(4N),99.9%(3N) (Eu2O3/REO) Molecular Weight: 351.92 Density: 7.42 g/cm3 Melting point: 2350° C Appearance: White powder with a little pink powder Solubility: Insoluble in water, moderately soluble in strong mineral acids Stability: Slightly hygroscopic Multilingual: Europium Oxid, Oxyde De Europium, Oxido Del Europio Application Europium(iii) oxide, also called Europia, is used as a phosphor activator, color cathode-ray tubes and liquid-crystal displays used in computer monitors and televisions employ Europium Oxide as the red phosphor; no substitute is known. Europium Oxide (Eu2O3) is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for Yttrium-based phosphors. Europium Oxide is used for producing fluorescent powder for color picture tubes, rare earth tricolor fluorescent powder for lamps, X-ray intensifying screen activators, etc. Europium Oxide is used as a red fluorescent powder activator for color televisions and fluorescent powder for high-pressure mercury lamps. Batch weight：1000,2000Kg. Packaging：In steel drum with inner double PVC bags containing 50Kg net each. Note:Relative purity, rare earth impurities, non rare earth impurities and other indicators can be customized according to customer requirements Specification
