Europium Metal Eu CAS 7440-53-1 For Reactor Control Material
Name: Europium metal Molecular formula: Eu
CAS: 7440-53-1 Molecular weight: 151.96
Description: Europium can be made into various forms: Europium foil, Europium block and Europium rod. The content of Europium in the earth's crust is 0.000106%, which is the rarest rare earth element. Europium mainly exists in monazite and bastnaesite. Europium is the least dense, softest and most volatile element in rare earth elements. Europium metal is the most active metal among the rare earth elements. At room temperature, europium immediately loses its metallic luster in the air and is quickly oxidized to powder. It reacts violently with cold water to generate hydrogen. Europium is usually prepared by vacuum distillation of the mixture of europium oxide and lanthanum.
