Europium Oxide Powder
Europium oxide (Eu2O3) is a white powder that is highly insoluble in water and thermally stable. It is formed by igniting europium metal. Due to the nature of oxide compounds, Europium oxide is not conductive to electricity. However, it is widely used for phosphor and fluorescent applications. Europium Oxide is hygroscopic and has carbon dioxide and moisture absorbing qualities in the atmosphere.
Europium Oxide Powder Applications
Europium oxide can be used as activator of red phosphor for color TV set, phosphor for high pressure mercury lamp, activator for rare earth luminescent material and activator for X-ray intensifying screen of trichromatic phosphor for lamp.
