Terbium is a chemical element with the element symbol Tb and the atomic number 65. In the periodic table it is in the lanthanide group and thus also belongs to the rare earth metals. Terbium is named after the first place where it was found, the Ytterby mine near Stockholm, as are yttrium, ytterbium and erbium. The discovery of the element terbium is very confused and not clarified until today. Generally, Carl Gustav Mosander is regarded as the discoverer, who examined the ytter earth discovered by Johan Gadolin in the early 1840s. However, the supposedly pure terbium compound was a mixture of several lanthanides (Bunsen). Pure terbium was not produced until the advent of ion exchange technology after 1945. Mosander derived the element name from the name of the Swedish mine Ytterby. Terbium occurs in nature only in compounds.

Extraction

After a complex separation of the other terbium companions, the oxide is reacted with hydrogen fluoride to form terbium fluoride. Subsequently, calcium is added to form calcium fluoride, which is reduced to terbium. The separation of the remaining calcium residues and impurities is

Fields of application

Due to its strongly magnetizing, phosphorescent properties, terbium offers a whole range of possible applications. For example, terbium in combination with zirconium oxide is of great importance in fuel cell technology. In addition to dysprosium, neodymium and europium, terbium is used to increase the coercivity. It is also used in phosphors to produce green color effects. In dentistry, it is used to manufacture all-ceramic systems.

Special features

The silver-gray rare earth metal is ductile and malleable. At temperatures above 1315 °C, α-terbium (hcp crystal lattice) transforms into β-terbium. In air, terbium is relatively stable, covering itself with an oxide layer. In the flame it burns to the brown terbium(III,IV) oxide (Tb4O7). It reacts with water to form a hydroxide with hydrogen evolution.
