History/Discovery
Discovering Thulium: A Milestone in Rare Earth Chemistry
Thulium was discovered in 1879 by Swedish chemist Per Teodor Cleve, who isolated it from the mineral erbia. Named after “Thule,” an ancient name for Scandinavia, Thulium remained a laboratory curiosity for many years. Due to its rarity and the difficulty of extracting it, practical uses for Thulium were limited. However, in the 20th century, scientists identified its value in laser technology and portable X-ray devices, transforming it from a mere chemical curiosity into an element with high-tech applications. Today, Thulium’s unique properties continue to support innovations in healthcare and nuclear science.
