Dysprosium Dy
Where is dysprosium used--or where does it impact your everyday life?
Dysprosium symbol: Dy
Atomic number: 66 Atomic Mass: 162.5
On periodic table: Lanthanide/rare earth Period number: 6
Melting point 1413 oC ( 2575.4 oF)

Used for supermagnets in hybrid car motors, for example the Ford Focus hybrids and the Toyota Prius. Neodymium is alloyed with other metals to make strong, lighter-weight motors. Terbium and dysprosium increase the heat resistance of the neodymium, so the neodymium is less likely to melt. Seen in the photograph is Biology teacher Ms. S with the engine bay of her hybrid car.
