Application---
Thulium Metal, is mainly used in making superalloys. Thulium has been used to create lasers. When stable thulium (Tm-169) is bombarded in a nuclear reactor it can later serve as a radiation source in portable X-ray devices. It also has potential use in ceramic magnetic materials called ferrites, which are used in microwave equipment. Thulium-doped calcium sulphate has been used in personal radiation dosimeters because it can register, by its fluorescence, especially low levels.

Thulium is a bright silvery-gray luster and can be cut by a knife. and belong to lanthanide element. It is the least abundant of the rare earths and its metal is easy to work. It slowly tarnishes in air, but is more resistant to oxidation than most rare-earth elements. It also has some corrosion resistance in dry air and good ductility.
