Europium oxide, melting point 2350 ℃, insoluble in water, soluble in acid, density 7.42g/cm3, chemical formula Eu2O3; Usually appears as white or slightly pink powder. It can evaporate together with steam, is alkaline, toxic, and irritating to the eyes, respiratory tract, and skin. It can absorb carbon dioxide in the air and form water-soluble salts with inorganic acids.
Europium is widely used in the manufacturing of reactor control materials and neutron protection materials. As a fluorescent powder for color televisions, it has important applications in europium (Eu) laser materials and atomic energy industries. Europium is one of the rarest rare earth elements. Its content on Earth is only 1.1 ppm. It is a soft, shiny, steel gray metal with strong ductility and malleability, which means it can be processed into various shapes. It looks and feels like lead, but it is slightly heavier.
Application field:
1. Used as a red fluorescent powder activator for color televisions and fluorescent powder for high-pressure mercury lamps.
2. Used for making dyes, rubber vulcanization accelerators, pharmaceuticals, pesticide fungicides, amino resins, ethylenediamine urea formaldehyde resins, metal chelating agents EDTA, etc.
3. Used as a solvent for fibrin, etc.
