Terbium

Terbium is a silvery-white rare earth element with the chemical symbol Tb and atomic number 65, belonging to the lanthanide series of the periodic table. It is classified as a critical mineral owing to its strategic importance in advanced technologies and the concentration of global supply. The element is primarily extracted as a by-product of rare earth mining operations, with China dominating global production and processing. Terbium's key applications include permanent magnets used in electric vehicles, wind turbines and other clean energy technologies, where it is often alloyed with dysprosium to enhance magnetic performance at elevated temperatures. It is also used in phosphors for fluorescent lighting and display screens, as well as in solid-state devices and magnetostrictive alloys. Global demand for terbium has grown alongside the expansion of renewable energy infrastructure and electric mobility, creating supply chain vulnerabilities for economies dependent on imports. Prices are volatile and sensitive to export policy changes in major producing nations. Exploration and development of rare earth deposits outside China, including projects in Greenland, Canada and the United States, aim to diversify supply and reduce geopolitical risk. Terbium was discovered in 1843 by Swedish chemist Carl Gustaf Mosander, who isolated it from yttrium-bearing minerals.
