Europium grades, chemical composition

General Characteristics

Europium is a soft rare earth metal of the lanthanoid group, atomic number 63, in the table of D.I. Mendeleev designated as Eu. Its atomic weight is nearly 152. It is a light luster metal. It is found as a concomitant element in the form of salts together with other rare-earth metals. The pure form was isolated in 1896 by French chemist E. Demarce, who named the metal after Europe. On an industrial scale today this metal is obtained by reducing Eu2 O3 oxide with carbon in a vacuum or by electrolysis of EuCl3 melt. Among the rare earth elements, europium is one of the most expensive. Like other nonferrous metals, it is supplied in the form of rounds, sheets and wires.

Physical qualities

It is a technologically advanced metal, easy to work: rolled, bent, drilled, cut, milled. Its melting point is 826°C, boiling point 1597°C, specific gravity 5.24 g/cm3. At 80 GPa and t° minus 271.5°C, europium becomes a superconductor.

Chemical properties

Europium is a fairly active element. Its valence is +2; +3. It replaces practically all metals in salts solutions, in the open air it is very quickly covered by oxide film. During storage it is placed in jars with kerosene or covered with a layer of paraffin.

Applications

In the composition of zirconium expands the width of capture of thermal neutrons and In nuclear boilers Eu2 O3, borate, hexaboride europium is part of the absorbing rods. With halogens, this metal forms photosensitive crystals. Unstable 154-europium can be used as radioactive fuel. In nuclear power, Eu2 O3, is needed in the thermochemical fission of deuterium and tritium. Europium in laser optics is used to generate orange radiation with a wavelength of 610 nm, serves as the basis for the creation of solid-state and liquid lasers.
