The physicochemical properties and preparation method of Europium oxide Eu2O3 powder

Europium oxide Eu2O3 powder physical and chemical properties

Europium oxide Eu2O3 is an inorganic compound with a pale pink powder. Insoluble in water, soluble in acid. It can volatilize with steam. It is alkaline and toxic. It is irritating to eyes, respiratory tract and skin. It can absorb carbon dioxide in the air and can form water-soluble salts with inorganic acids.

Overview of Europium Oxide Eu2O3 Powder

Europium oxide ((Eu2O3) is also an auxiliary for the production of fluorescent glass. Fluorescence is used as anti-counterfeiting phosphor on Euro banknotes. Oxidation p has two common structures: monoclinic structure and cubic structure, similar to manganese oxide (III) oxidation can Reacts with acid to form the corresponding Euro (III) salt.

Europium oxide ((Eu2O3) is a red-white crystalline powder with a melting point of 2050°C, insoluble in water, soluble in inorganic acids, and stable in dry and humid air. It has a NAC1 structure, ferromagnetism and high resistivity of T-68K. .Semiconductor. Excessive oxygen becomes an insulator. Excessive becomes metal.

Preparation method of europium oxide Eu2O3 powder

The extraction method uses the rare earth chloride solution obtained by processing monazite or mixed rare earth ore as the raw material. Extraction with P204-kerosene-HCL-ReCl3 system, first grouping of neodymium and samarium, the raffinate is used to extract light rare earths, samarium and heavy rare earths are extracted into the organic phase, and then the middle rare earths are back-extracted with 2.0mg/L HCl to obtain a medium After the rare earth samarium enrichment is reduced by zinc powder, europium is extracted by the alkalinity method, and then precipitated with oxalic acid, separated, dried, and burned to obtain europium oxide.

toxicity

The salt of rare earth elements can reduce the content of prothrombin, make it inactivated, and inhibit the production of thrombin, precipitate fibrinogen, and catalyze the decomposition of phosphoric acid compounds. The toxicity of rare earth elements decreases with the increase of atomic weight. You need to wear a gas mask when you work. If there is radioactivity, special protection should be carried out. The dust should be prevented from scattering.

Europium Oxide Eu2O3 Powder Application

For europium oxide, phosphors can be used as a raw material.

Europium oxide is used in the fields of color cathode ray tubes, color TV picture tubes, computer monitors, tri-color fluorescent lamps, new long afterglow displays, and stimulated emission phosphors in new X-ray medical diagnostic systems;

Europium oxide can also be used to make colored lenses, filters and magnetic bubble storage devices;

Europium oxide is also a very important material in nuclear reactor control, shielding and structural materials.

Europium oxide is widely used as red or blue phosphors for televisions and fluorescent lamps, and it can also be used as an activator for yttrium-based phosphors. P oxide is also an additive for the production of fluorescent glass.
