Terbium is never found in nature as a free element, but it is contained in many minerals, including cerite, gadolinite, monazite, xenotime and euxenite. Swedish chemist Carl Gustaf Mosander discovered terbium as a chemical element in 1843. He detected it as an impurity in yttrium oxide (Y 2 O 3).
Terbium occurs in many rare-earth minerals but is almost exclusively obtained from bastnasite and from laterite ion-exchange clays. It is also found in the products of nuclear fission. Terbium is one of the least abundant of the rare earths; its abundance in Earth’s crust is about the same as thallium.

Where is Terbium Found. Being one of the rarest elements in the lanthanides group, it does not occur in a free state in nature [4]. However, it can be obtained from the minerals bastnaesite and monazite through solvent extraction and ion exchange [1].
Terbium is not found free in nature but is extracted from minerals such as xenotime, euxenite, and monazite. It is relatively scarce, with an abundance in the Earth’s crust estimated to be about 1.2 mg/kg. The primary source of the element consists of clay from southern China. A newer supply occurs off the coast of Japan.
Terbium was discovered in 1843 by Carl Gustaf Mosander. He found it as impurity in yttrium oxide Y 2 O 3. It was not isolated until the discovery of ion exchange method. Yttrium and terbium are named after the name of village Ytterby (Sweden) [1].
Terbium is a soft, silvery rare earth metal with element symbol Tb and atomic number 65. It isn't found free in nature, but it occurs in many minerals and is used in green phosphors and solid state devices. Get terbium facts and figures.
The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. Terbium is never found in nature as a free element, but it is contained in many minerals, including cerite, gadolinite, monazite, xenotime and euxenite.
- The element terbium was first discovered in 1843 by Carl Gustaf Mosander, a Swedish chemist. - It was found as an impurity in yttria, which is an oxide of yttrium. - The name "Terbium" was derived from Ytterby, a village in Sweden where the mineral containing terbium was originally found.
terbium, Chemical element in the lanthanide series, chemical symbol Tb, atomic number 65. It was named after the Swedish town of Ytterby, where it was discovered in 1843. One of the least abundant of the rare earth metals, terbium is silvery white in its metallic form.
