Samarium, one of the rare earth metals, is relatively unreactive
air, although it will oxidize if left exposed for many days. ACI
Alloys can supply pure samarium sputtering targets and evaporation
pieces, as well as many samarium alloys. See samarium in our
"materials made" page for an idea of our capabilities--also try
searching alphabetically on each of the element symbols in
the material you are looking for.
The MSDS for samarium can be found here.
