Europium Metal (Eu)-Granules

Europium Metal (Eu)-Granules introduce:

Characteristic




Europium is a chemical element with the symbol Eu and atomic number 63. Europium is the most reactive lanthanide by far, having to be stored under an inert fluid to protect it from atmospheric oxygen or moisture.




Phase at STP： solid

Melting point： 1099 K (826 °C, 1519 °F)

Boiling point： 1802 K (1529 °C, 2784 °F)

Density (near r.t.)： 5.264 g/cm3

when liquid (at m.p.)： 5.13 g/cm3

Heat of fusion： 9.21 kJ/mol

Heat of vaporization： 176 kJ/mol

Molar heat capacity： 27.66 J/(mol·K)




Application




Europium has no significant biological role and is relatively non-toxic compared to other heavy metals. Most applications of europium exploit the phosphorescence of europium compounds. Europium is one of the rarest of the rare earth elements on Earth.
