Neodymium – 60
Neodymium is a light rare earth metal and one of the most reactive elements in the group. It is commercially refined from monazite and bastnasite.
High-strength magnets for electrical motors, microphones, cell phones, speakers, hard drives, regenerative braking systems for hybrid cars, anti-lock brakes, wind turbines, hydro power turbines. Anti-glare car light glass and mirrors.
Solid-state neodymium light laser for welding, drilling, material processing, medical applications. Neodymium capacitor boosts power of cell phones. Nickel metal hydride (NiMH) batteries. Automotive catalytic converters. Manufacture of high-strength glass substrates for hard disks. Fluid cracking catalysts (FCCs) used to refine heavy oils and tars (ie. shale and oil sands sources) into light fuels like gas, diesel, and jet fuel.
