Europium
Europium (CAS 7440-53-1, Eu, MW 151.96) is a soft, silvery-white, malleable rare-earth metal. Known for its distinctive fluorescence, Europium metal finds critical applications in phosphors for television screens and lighting, as a nuclear reactor control material due to its neutron absorption cross-section, and in various catalysis and materials science research endeavours. Tech Serve Solutions supplies Europium ingot at 99.9% trace metals basis.
Phosphor Production
Europium compounds are essential activators in phosphors, providing the red and blue colours in cathode ray tube (CRT) televisions and fluorescent lighting. This luminescent property is key to display technologies.
Nuclear Applications
With a high neutron absorption cross-section, Europium metal is utilised in nuclear reactors as control rods or burnable neutron poisons. Its isotopes can also serve as neutron sources.
Catalysis and Materials Science
Europium's unique electronic structure makes it a subject of interest in catalysis research and the development of novel materials with specific magnetic or optical properties. It is employed in various chemical synthesis pathways.
Specialty Glass and Ceramics
Doping glass and ceramics with Europium can impart specific optical characteristics, such as phosphorescence or UV absorption, for specialised applications.
