Lanthanum, one of the rare earth metals, is somewhat reactive in air. It forms a purplish oxide within a few days or weeks. ACI Alloys can supply pure lanthanum targets and evaporation pieces packed in either a dessicant or in mineral oil. Many lanthanum alloys are unreactive and, we provide them in protective packaging only as needed. See lanthanum 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 lanthanum can be found here.
