Categories: 21 Feb 2012

Praseodymium is refined commercially from monazite and bastnasite mineral deposits and has a wide range of uses.


Colouring pigment for ceramic tile and glass. Photographic filters, airport signal lenses, welder’s glasses, premium quality mirrors. Phosphor coating for compact fluorescent lamps (CFL). Magnets for hybrid car regenerative braking systems and motors. Pollution control catalysts for internal combustion engines. Nickel metal hydride (NiMH) batteries. Glass polishing for cathode ray tubes (CRT), plasma (PDP), and liquid crystal (LCD) screens. Used in magnets for electrical motors, microphones, cell phones, speakers, hard drives, regenerative braking systems for hybrid cars, anti-lock brakes, wind turbines, hydro¬†power turbines. 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.
