Thulium

Thulium (Tm) is a silvery-gray lanthanide metal, one of the rarest naturally occurring rare earth elements. It has a melting point of 1545 °C and demonstrates moderate reactivity, particularly oxidizing slowly in moist air. Thulium is mainly obtained from monazite and xenotime ores and is extracted using solvent extraction and ion exchange methods.

Goodfellow's high-purity Thulium materials are designed to meet the exacting requirements of advanced research and industrial applications. Available in forms such as foil, powder, rod, and sputtering target, thulium is valued for its unique magnetic properties and strong luminescence. This rare earth metal exhibits ferromagnetic behavior below 32 K and becomes paramagnetic above 56 K. Thulium finds critical applications in the laser technology, medical imaging, and electronics industries. It plays a vital role in the production of high-performance lasers for surgical procedures and as a component in portable X-ray devices for medical diagnostics. In the electronics sector, thulium is used to enhance display technologies, particularly in the development of high-definition screens with improved color accuracy. Goodfellow's thulium products support cutting-edge research in areas such as high-temperature superconductors and next-generation optical communication systems. Their distinctive properties make them indispensable for scientists and engineers advancing materials science, particularly in applications requiring specialized magnetic characteristics and precise optical capabilities.
