Thulium Metal Introduction
Thulium metal is a bright, lustrous, soft, malleable, silvery rare earth metal, a member of the periodic table’s lanthanide group. It is the second least abundant of the lanthanides only after promethium. It can be cut with a knife. Thulium Metal is mainly used in making superalloys. It has some application in ferrites (ceramic magnetic materials) used in microwave equipment and as a radiation source of portable X-ray. Thulium potentially has usage in ferrites, ceramic magnetic materials that are used in microwave equipment. It is used in arc lighting for its unique spectrum. Thulium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs, and powder.

Application of Thulium Metal
Portable X-ray devices use thulium that has been bombarded in a nuclear reactor as a radiation source. Thulium-170 is also gaining popularity as an X-ray source for cancer treatment via brachytherapy. Also, Holmium-chromium-thulium triple-doped Yttrium aluminum garnet is an active laser medium material.
Packaging of Thulium Metal
1. Packed in iron drums, lined with a single layer of plastic bags and protected by argon, each barrel weighs 50kg or 250kg.
