When and How was Dysprosium Discovered In 1886, the element dysprosium was discovered by de Boisbaudran who carried out a series of research on the compound yttrium oxide involving endless precipitations on a marble slab of the fireplace at his home in Paris [1] . Discovered by. This element with symbol Dy is abundantly found in nature and even found in many minerals such as gadolinite, xenotime, euxenite, fergusonite, blomstrandine and polycrase, which can also be called as sources of Dysprosium. Dysprosium is used with argon in mercury-vapor lamps to give a higher light output and balance the color spectrum. and the oldest existing sample from that era was from 6,000 B.C.E. History: Dysprosium was discovered in 1886 by French chemist Andre Lecoq de Boisbaudran. In addition to samarium, Lecoq discovered gallium in 1875 and he went on to isolate gadolinium in 1885 and dysprosium in 1886. Neither the metal nor the oxide was available in pure form until ion exchange separation and metallographic reduction techniques were developed by Spedding and associates in 1950. William Perkin was a young scientist who discovered a new synthetic dye and also realised its commercial potential, thus founding the chemical industry. Element Dysprosium - Dy. The origin of the name comes from the Greek word dysprositos meaning hard to obtain. The element is found in bastnasite, monazite, and other minerals. Here are interesting dysprosium facts, including its history, uses, sources, and properties. While it was not understood to be an element at that time, the first element discovered was copper (Cu) due to the fact that its oldest known use was in 9,000 B.C.E. Dysprosium was discovered by Paul-Émile Lecoq de Boisbaudran (FR) in 1886. The rare earth is a key ingredient for emerging technologies and is used in magnets for electric vehicles. elemental form, CAS 7429-91-6, dysprosium has a silvery-white appearance.
