Thulium Pellets

Thulium Pellets combine high purity, controlled composition, and valuable optical and magnetic properties in a compact, machinable form optimized for precision dosing in metallurgical and research processes. Their shape enables consistent handling for vacuum deposition, crystal growth, and alloy production. Industries employ thulium pellets to dope YAG lasers used in medical surgery, metal cutting, and environmental monitoring systems, as well as in advanced magnet fabrication and specialized catalysts. The pellets’ stability under vacuum and high temperature ensures reliable evaporation rates in thin-film coating systems. In research, they are used to study magneto-optical effects, neutron shielding properties, and the creation of upconversion phosphors for photonics. This combination of material properties and pellet form versatility supports repeatable performance across demanding industrial and laboratory environments.
