Product Name:Europium(III) oxide
English Name:Europium(III) oxide
CAS No.:1308-96-9
Aliases:Europium oxide, Europium sesquioxide, Europium trioxide
Molecular Formula:Eu2O3
Physical Properties:Relative molecular mass 351.93; white to slightly pink powder; melting point approx. 2297°C, boiling point approx. 3790°C, relative density 7.42 g/cm³; insoluble in water, soluble in mineral acids; readily absorbs moisture and carbon dioxide in air; cubic crystal system (bixbyite-type structure).
Uses:Used as an activator/raw material for red phosphors in color television tubes, fluorescent lamps and LEDs; also used as a neutron-absorbing material in nuclear reactor control rods and as a dopant in optical glass, ceramics and catalysts. High-purity europium(III) oxide is widely used to prepare rare-earth luminescent materials.
