In its oxide form, the soft heavy metal is a black brown powder. In metal form, terbium is so soft that it can be cut with the knife. It is very unnoble, but relatively durable exposed to air. Terbium usually occurs in conjunction with other lanthanids.
Terbium is used in the production of semiconductors and serves as an activator for fluorescent materials. Together with zircon dioxide, it works in one of the most important industries of the future: As a stabilizer of high-temperature fuel cells. In addition, the oxide is added to the green fluorescent in picture tubes and fluorescence lamps. Due to its ferromagnetic “talents”, terbium is also suitable for the production of magnetic components: Especially in neodymium iron boron magnets, it increases performance even further.
The widespread use of terbium in high-tech products such as fuel cells is driving growing terbium demand.
The future prospects for terbium are similar to that for dysprosium, neodymium or the enormously important europium for light sources. The US Department of Energy published a study in late 2011, predicting a supply gap for both terbium, similar to dysprosium, in the medium and long term. Terbium is therefore ideal as part of an alternative investment in rare earths. Investors can benefit massively from the long-term opportunities offered by this strategic commodity.
Do you have any questions or would you like to invest in terbium oxide? We are happy to talk about everything in a personal conversation.
