Terbium

Belonging to the so-called heavy rare earths, terbium is significantly rarer and more expensive to extract than the light representatives of the raw material group. Terbium is one of the most expensive rare earth elements and also plays an important role in the energy and transport transition.

Areas of application

Magnet with rare earths
Semiconductors
Green hydrogen

The addition of terbium can improve the performance of permanent magnets with neodymium-iron-boron and increase the operating temperature from just under 80 to 200 degrees Celsius. NdFeB magnets are increasingly in demand for applications such as electromobility, wind power, consumer electronics and military technology. Terbium is also used for doping semiconductors and as a stabiliser for fuel cells. Other areas of application include phosphors and lasers as well as ceramics for dentistry.
