High Purity Europium Oxide Eu2O3 Powder CAS 1308-96-9，99.9%

About Europium Oxide Eu2O3 Powder :
Europium (III) oxide Eu2O3 is a compound of europium and oxygen. Europium oxide is widely used as red or blue phosphors for television sets and fluorescent lamps, and as an activator of yttrium-based phosphors. It is also an auxiliary agent for the production of fluorescent glass. Europium fluorescence is used as an anti-counterfeiting phosphor on euro banknotes. Europium oxide has two common structures: monoclinic and cubic structures similar to manganese (III) oxide. Europium oxide can react with acids to form corresponding europium (III) salts.
Europium oxide Eu2O3 is a reddish-white crystalline powder. The melting point is 2050 . Insoluble in water, soluble in mineral acids, stable in dry and wet air, is NAC1 type structure. At T- 68K are ferromagnetic and high resistivity substances. The semiconductor. Oxygen becomes an insulator in excess. Europium in excess becomes a metal conductor.

is a trusted global Europium Oxide Eu2O3 Powder supplier . Feel free to send an inquiry about the latest Europium Oxide price at any time.

Performance of Europium Oxide Eu2O3 Powder:
Europium Oxide powder is a highly insoluble thermally stable Europium source suitable for glass, optic and ceramic applications. Europium oxide powder has a cubic structure similar to that of manganese oxide and may be formed by the ignition of europium metal. Europium oxide forms europium salts when it reacts with acid. Europium Oxide powder is generally immediately available in most volumes. Ultra-high purity and high purity compositions improve both optical quality and usefulness as scientific standards.

How is Europium Oxide Eu2O3 Powder Produced?
Europium oxide was prepared from europium trioxide by reducing europium trioxide in molybdenum at 800 ~ 2000. Europium oxide can also be produced by reducing europium trioxide with lanthanum metal.

Applications of Europium Oxide Eu2O3 Powder :
Europium oxide can be used as a raw material for phosphors.
Europium oxide is used in color cathode ray tubes, color TV picture tubes, computer displays, trichromatic fluorescent lamps, new long afterglow displays and other fields, as well as the stimulated emission phosphors of new X-ray medical diagnostic systems;
Europium oxide can also be used in the manufacture of colored lenses, optical filters, magnetic bubble storage devices;
Europium oxide is also a very important material in the control, shielding and structural materials of atomic reactors.
Europium oxide is widely used as a red or blue phosphor for television and fluorescent lamps, and can also be used as an activator for yttrium-based phosphors. Europium oxide is also an additive in the production of fluorescent glass.

Storage Condition of Europium Oxide Eu2O3 Powder:
The damp reunion will affect Europium Oxide Eu2O3 Powder dispersion performance and using effects, therefore, scandium oxide should be sealed in vacuum packing and stored in cool and dry room, the scandium oxide can not be exposure to air. In addition, the Europium Oxide Eu2O3 Powder should be avoided under stress.

Packing & Shipping of Europium Oxide Eu2O3 Powder:
It is packed in double plastic bags inside, which can be filled with argon in a vacuum; it can be vacuumed and filled with argon for protection.
Europium Oxide Eu2O3 Powder packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Europium Oxide Eu2O3 Powder shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
