Thulium Metal/ Sputtering Target

Thulium Metal/ Sputtering Target

CAS #: 7440-30-4
Linear Formula: Tm
EC No.: 231-140-2

Thulium  Metal is a silver-gray active metal with a molecular formula of Tm. The powder is easily self-igniting in the air and easily soluble in acid, Insoluble in water, After exposure to oxygen in the air, it is very easy to exotherm into oxidized rare earth, The package is sealed and must not be in contact with air. It should be stored separately from oxidants, acids, halogens, and food chemicals. Avoid mixing.

Application: As a raw materials for other Special alloys ,Hydrogen storage alloy additives and Magnetostrictive material,etc.
