Erbium is a rare-earth element. Therefore, it has properties similar to other rare-earth elements. However, it also has some properties that make it different from other rare-earth elements.
Erbium has a hexagonal, and closely packed lattice system, is relatively soft, and has about 29 radioisotopes. Its standard atomic weight is 167.259.
Most properties of erbium are due to its atomic number and periodicity. On the periodic table, it belongs to period 6, f-block. It is solid at room temperature. Its melting point is 1802 K, and its boiling point is 3141 K.
Erbium’s density varies with its state. When it is solid, its density is 9.07g/cm3, but when it is liquid, it becomes 8.86g/cm3.
Erbium undergoes several chemical reactions. It tarnishes slowly in a humid atmosphere and is highly reactive with all halogens to form compounds with colors ranging from pink to violet. It is soluble in dilute sulfuric acid and combusts to form erbium(iii)oxide. On reacting with cold or hot water, it forms erbium hydroxide. Its reaction with the latter is fast, while its reaction with the latter is slow.
In addition, Erbium has a very high magnetic strength. It is ferromagnetic under 19K, antiferromagnetic between 19 and 79K, and paramagnetic at about 80K. It has a silvery appearance, but its salts have a pinkish color that makes them attractive.
Erbium's everyday uses are varied. It is commonly used as a photographic filter, and because of its resilience it is useful as a metallurgical additive. Other uses:
Used in nuclear technology as a nuclear poison, as in neutron-absorbing control rods.
When added to vanadium as an alloy, erbium lowers hardness and improves workability.
Erbium oxide has a pink color, and is sometimes used as a colorant for glass, cubic zirconia and porcelain. The glass is then often used in sunglasses and cheap jewelry.
Erbium-doped optical silica-glass fibers are the active element in erbium-doped fiber amplifiers (EDFAs), which are widely used in optical communications. The same fibers can be used to create fiber lasers. Co-doping of optical fiber with Er and Yb is used in high-power Er/Yb fiber lasers, which gradually replace CO2 lasers for metal welding and cutting applications. Erbium can also be used in erbium-doped waveguide amplifiers.
An erbium-nickel alloy Er3Ni has an unusually high specific heat capacity at liquid-helium temperatures and is used in cryocoolers; a mixture of 65% Er3Co and 35% Er0.9Yb0.1Ni by volume improves the specific heat capacity even more.
