Description

Soft, silvery-white, malleable, ductile metal.

Uses

It is used in the electodes of high-intensity, carbon-arc lights. Also used in the production of high-grade europium metal. Because it gives glass refractive properties, it is used in expensive camera lenses.

Name Origin

Greek: lanthanein (to be hidden).

Sources

Found with rare earths in monazite and bastnasite. Monazite sand typicall contains 25% lanthanum.
