Europium Oxide Eu2O3 Powder CAS 1308-96-9

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, and 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.

Performance of Europium Oxide Eu2O3 Powder:

Europium Oxide powder can be described as a very insoluble and thermostability Europium source suitable for glass, optics, or ceramic uses. Europium oxide powder has a cubic structure similar to 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 and high-purity compositions improve optical quality and usefulness as scientific standards.

Europium oxide is a rare earth metal oxide with the formula Eu2O3. It has the characteristics of high refractive index, high density, hardness, high thermal conductivity, and high corrosion resistance, so it has a wide range of applications in optics, electronics, catalysts, and medical fields. The following are the main production methods of europium oxide:

Europium metal method: The metal is heated to a high temperature in the air, which can be oxidized to produce europium oxide. The advantage of this method is that the process is simple and easy to control, but it needs to use a large amount of metal europium raw materials, and the production cost is high.

Europium hydroxide method: Europium hydroxide is added to hydrogen peroxide for reaction to obtain europium oxide. Europium Oxide powder provides a thermostability Europium source that can be used in glass, optics, and ceramic applications., but it requires a large amount of Europium hydroxide raw material and high production cost.

Europium oxychloride method: The decomposition of europium oxychloride by heating can produce europium oxide. The benefits of this technique are the mild reaction conditions and easy operation, but it requires a large amount of europium oxychloride raw material and high production cost.

High-temperature decomposition method: Europium carbonate or hydroxide is added to carbon and heated to high temperatures to produce simple europium and carbon dioxide. Elemental europium then reacts with chlorine gas to produce europium chloride. Europium chloride then reacts with hydrogen peroxide to produce europium chloride oxide. Finally, it heats to decompose europium chloride oxide to obtain europium oxide. The benefits of this method are a low level of reaction and simple operation, but it needs to use a lot of carbon and chlorine raw materials, and the production cost is high.

Ion exchange method: using rare earth metal salts as raw materials, dissolving them in solvents, and then adding ion exchangers to react to produce rare earth ion exchange resin and ammonium chloride. The resulting rare earth ion exchange resin is heated to a high temperature and burned to produce europium oxide. The advantages of this method are low production cost and easy industrial production, but the need to use a lot of rare earth metal salt raw materials.

Analytical reagents: Europium oxide can serve to act as an analytical agent to aid in the determination of elemental rare earths as well other elements made of metals and is used extensively for the analysis of trace elements in the fields of geology, environmental protection as well as chemical industry areas. By using europium oxide as a reagent, the content of trace elements in samples can be more accurately determined, which provides important data support for scientific research.

Catalyst: Europium oxide can be used as a catalyst in petrochemicals, automobile exhaust purification, and other fields, improving catalytic efficiency and selectivity. In these fields, the catalytic action of erbium oxide can reduce the activation energy of the reaction, accelerate the chemical reaction rate, and improve the selectivity of the product, resulting in more efficient and environmentally friendly chemical production.

Optical materials: Europium oxide has the characteristics of high light transmittance, high refractive index, and low scattering, and can be used to prepare optical materials, such as lenses and prisms. In optics, these properties of europium oxide make it an important optical material widely used in optical instruments, lasers, optoelectronic devices, and other fields.

Electronic Materials: Europium oxide has good electrical conductivity and thermal stability and can be used to prepare electronic materials, such as resistors, capacitors, etc. In these fields, the conductivity and thermal stability of europium oxide can meet electronic components' requirements and improve electronic equipment's performance and stability.

Rare earth permanent magnet material: Europium oxide can form rare earth permanent magnet materials with other rare earth metal elements, such as GdCo5, Gd2Co17, etc. Permanent magnets offer the benefits of having a high Remanence, high coercivity and a product with high energy that provides crucial technical support in the fields of generators, motors and sensors. Within rare earth-permanent magnets, applying europium oxide can improve the motor's efficiency, reduce energy consumption, and increase the sensor's sensitivity and accuracy. Sensor. It also improves the sensitivity and accuracy of the.

Medical field: Europium Oxide also has numerous applications in the medical field, such as contrast agents in magnetic resonance imaging (MRI). Due to its paramagnetism, europium oxide can shorten the rotation period of hydrogen atoms, thus improving the resolution and contrast of imaging. In addition, europium oxide can also be used to prepare drug carriers and targeted therapy, providing new possibilities for medical science and technology development.

High-temperature structural materials: Since europium oxide has the highest melting point and a high-temperature conductivity, hardness, and high corrosion resistance, it can be utilized as an extremely strong structure material in conditions of high temperature. For example, europium oxide can be used to make high-temperature containers such as furnace tubes and crucibles in high-temperature furnaces. It can also make high-temperature devices such as high-temperature sensors and high-temperature bearings.

Luminous material: Europium oxide has the advantages of high brightness, high color temperature, and low attenuation and can be used as a luminous material in display, lighting, and other fields. At the same time, europium oxide can also be combined with other rare earth elements to prepare new luminescent materials with better properties.
