Europium

Europium is a chemical element, which was named after the continent of Europe. It is a moderately hard silvery metal which readily oxidizes in air and water. It has no significant biological role and is relatively non-toxic compared to other heavy metals. It is a dopant in some types of glass in lasers and other optoelectronic devices. It is also used in the manufacture of fluorescent glass. Europium oxide is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors. Europium fluorescence is used to interrogate biomolecular interactions in drug-discovery screens. It is also used in the anti-counterfeiting phosphors in Euro banknotes.

Europium Metal Purified 99.9%

Europium metal is steel grey metal of body-centered cubic lattice, which is soft and ductile. It is rare earth element, which is available with powder, foil, rod, piece, ingot, granule, slug, sputtering target. Eu react rapidly with oxygen and water. When heating to 150~180℃, it fires in air. Europium powder tend to ignite, which is most active among rare earth metals. There are two production method, reduction and distillation. Distilled Eu piece is dendritic with higher purity than reduced Eu metal.

Europium Oxide Industrial Grade 99.9%

Europium oxide is white powder, which is a kind of rare earth oxides. it is of NaCl type structure and stable in dry or moisture air. It is insolube in water and alkali solution. However dissolve in inorganic acid( except HF and H3PO4), which form corresponding salts. Europia absorb CO2 and moist in air and form subcarbonate salt.

Applications

Europium(III) oxide is raw material for fluorescent powder. It is for color cathode ray tube, colour TV kinescope, computer display, three band fluorescent lamp and new long-lasting displayer. It is also raw material for stimulated luminescent powder of new X-ray medical diagnositc system.

Europia apply to make colored lens, opitcal filter, magnetic bubble storage device. It is also important for  control materials, shielding material and structural material in atomic reactor.

Europium trioxide is mainly for fluorescent powder of  colored TV, terminal display, X-ray intensifying screen and fluorescent lamp. It is also pigment for glasses. It can make glass reddish orange and radiation protective glass. Europia is additive for silica fiber.

Europium trioxide is activating agent for many phosphors, as Eu3+ for colorimetric tube Y2O3 or Y2O2S, high pressure mercury lamp YVO4.

Europia apply as neutron absorber in nuclear industry.
