Praseodymium Properties

Description

Praseodymium is a chemical element. It is used as an alloying agent with magnesium to create high-strength metals that are used in aircraft engines. It forms the core of carbon arc lights which are used in the motion picture industry for studio lighting and projector lights. Praseodymium compounds give glasses and enamels a yellow color. Silicate crystals doped with praseodymium ions has been used to slow a light pulse down to a few hundred meters per second. Praseodymium alloyed with nickel has such a strong magnetocaloric effect that it has allowed scientists to approach within one thousandth of a degree of absolute zero.
