Nanografi Nano Technology Facts about Europium Powder *Europium is the least abundant of the rare earth elements. It is also the most reactive one. Europium is found in many minerals such as xenotime, monazite, bastnasite, and loparite. It is not found in nature as a free element. Europium was isolated in 1901 and is named after the continent of Europe. *Europium is silvery metal that instantly oxidizes in air. It is the most reactive of the rare earth metals and ignites in air at temperatures in excess of 150 degree to 180 degree. Europium resembles calcium in its reaction with water. Also, Europium metal is the most reactive metal of all rare earth elements. *Europium is about as hard as lead and is quite ductile. *Europium is considered to be mildly toxic. Europium powder is considered to be a fire and explosion hazard. *Europium is used in the printing of euro banknotes. It glows red under UV light, and forgeries can be detected by the lack of this red glow.

It is also used in making thin super-conducting alloys. [email protected]
