Europium Oxalate Hydrate

Europium oxalate hydrate powder is a white, powdery substance with cubic crystal structure, with the chemical formula Eu₂(C₂O₄)₃・xH₂O, slightly soluble in water, and it has important applications in the fields of petroleum, environmental protection catalysts, and synthesis of luminescent materials. It has a high melting point and is chemically stable, but will undergo chemical reactions under specific conditions.

Properties

Chemical formula: Eu₂(C₂O₄)₃・xH₂O, which contains oxalate ion and europium ion.

Molecular weight: 567.99 (exists in hydrate form, exact molecular weight may vary somewhat depending on water content)

Boiling point: 365.1°C (at 760mmHg)

Stability: sensitive to air and humidity, need to be sealed and stored in a dry, cool place, avoid prolonged exposure to air.

Reactivity: Chemical reaction can occur under certain conditions, for example, it will decompose when heated, and corresponding chemical reaction may occur when contacting with other chemical substances, the specific reaction depends on the nature of the substances contacting with it.

Magnetic properties: the element europium itself has certain magnetic properties, in europium oxalate hydrate, due to the presence of europium ions, the compound will also show a certain degree of magnetism, but the specific magnetic parameters will be affected by factors such as the purity of the compound, the crystal structure and the temperature.

Optical Properties: It has a certain application potential in optics. Europium ion has a unique electronic structure, which can produce specific luminescence phenomenon under certain excitation conditions, so europium oxalate hydrate can be applied in the preparation of luminescent materials, for example, in the field of phosphor, glow-in-the-dark materials and so on.

Applications

As precursor of luminescent materials: it is used in the production of luminescent materials such as phosphor, which has important applications in the fields of lighting, display, laser and so on. For example, some of the phosphors used in colour TVs, fluorescent lamps and other equipment may be prepared from europium oxalate hydrate.

For catalyst synthesis: it can be used as precursor material for the synthesis of europium-based catalysts, which plays a catalytic role in some chemical reactions.

In the field of material science: it can be used in the preparation of special optical glass, ceramic materials, etc., and its optical properties can be used to improve the performance of materials. For example, in the preparation of some optical glass, the addition of europium oxalate hydrate can enhance the luminescence of the glass or change its optical absorption properties.
