Description
Silvery-white, rare-earth metal that oxidizes easily in air.
Uses
Used in making artificial ruby for lasers. Also in ceramics and for a special lens with praseodymium. Also to produce bright purple glass and special glass that filters infrared radiation. Makes up 18% of Mich metal, which is used in making steel.
Sources
Made from electrolysis of its halide salts, which are made from monazite sand.
Pronounciation (English)
