Applications:
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, polycrase
and xenotime. It is relatively stable in air at room temperature. It dissolves quickly with the evolution of hydrogen
in 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 improve
the 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.
