Cerium, one of the rare earth metals, is relatively reactive
in air. It forms a signature green oxide within a few hours. ACI Alloys
can supply pure cerium targets and evaporation
pieces packed in either a dessicant or in mineral oil. Many cerium
alloys are less reactive. See cerium 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 cerium can be found here.
