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