Application---

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.
