Erbium oxide 

 Name: Erbium oxide; erbium oxide 

 Information: 
 Molecular formula: Er2O3 
 Molecular weight: 382 
 CAS: 
 Nature: Er2O3 pink powder. Density of 8.64. Melting point 2378 ℃. Boiling point of 3000 ℃. Insoluble in water, soluble in acid. Mainly used as additives of yttrium iron garnet materials and nuclear reactor control, but also for the manufacture of specialty glass and absorb the infrared light-emitting glass, the glass is also used as a coloring agent. Nitric acid or sulfuric acid by the erbium-doped with alkali solution, after separation, derived from burning. Only Er2O3 a stable compound. Is body-centered cubic and monoclinic powder two structures. Er2O3 magnetic moment is also large, as 9.5MB. With other nature and the preparation method on the lanthanides. Making pink glass.
