Dysprosium is named from the Greek word dysprositos meaning ‘hard to get’. It is black brown metal powder. It is found in minerals such as fergusonite, monazite, bastnäsite, blomstrandine, euxenite, gadolinite, polycraseand xenotime. It is relatively stable in air at room temperature. It dissolves quickly with the evolution of hydrogenin mineral acids. Dysprosium has one of the highest magnetic strengths of the elements.Dysprosium powder has applications in electronics for data storage because of its magnetic properties. It is used in various data storage applications such as in compact discs. Dysprosium is substituted in many magnets to improvethe corrosion resistance of the magnets. It has also applications in optics as a dopant in glass and optical fibers. It is also added to advance optical applications as it emits 470-500 nm and 570-600 nm wavelengths. |
