The element symbol Er, atomic number 68, is located in the periodic table of chemical elements on the 6th cycle, the lanthanide (IIIB) 11, the atomic weight 167.26, the element name comes from the discovery site of yttrium. Erbium 1843 Swedish scientist mosander used a graded precipitation method to find the oxide of erbium from yttrium soil, which was officially named in 1860. The content of erbium in the earth's crust is 0.000247%, which is found in many rare earth ores. There are six natural isotopes: erbium 162, 164, 166, 167, 168, 170.
Erbium is silver-white metal; Melting point of 1529°C, the boiling point of 2863°C, the density of 9.006 g/cm & sup3;; Erbium is antiferromagnetic at low temperatures and is close to extinction.
It is strongly ferromagnetic at zero and is a superconductor. Erbium is oxidized slowly by air and water at room temperature, and erbia is rose red. Erbium can be used as reactor control material; Erbium can also be used as an activator of certain fluorescent materials. The first ionization energy is 6.10 electron volts. The chemical properties and physical properties of holmium and dysprosium are almost identical. Silver gray metal, soft, insoluble in water, soluble in acid. The salts and oxides are pink to red. The isotopes of erbium are: 162Er, 164Er, 166Er, 167Er, 168Er, 170Er.
