About Ultra Thin Lanthanum Nanoscale Foil

American Elements' Nanometal™ nanoscale foil manufacturing unit produces ultra thin Lanthanum foil as thin as only 50 nm thick in diameters up to 910 mm. Typically, foils are in thicknesses from 20 nm to 1000 nm, 1 micron, 2 micron, and up to a few microns thick. Nanometal™ ultra thin foil can also be produced on a substrate with a parting agent to permit removal by floating and can then be mounted on frames. Frames may be washers, rings, or more-complicated assemblies. For foils >1 micron thick see our Lanthanum Foil page. We also produce Lanthanum as rods, powder and plates. Other shapes are available by request.

The number of electrons in each of lanthanum's shells is [2, 8, 18, 18, 9, 2] and its electron configuration is [Xe] 5d¹ 6s². The lanthanum atom has a radius of 187 pm and a Van der Waals radius of 240 pm. Lanthanum was first discovered by Carl Mosander in 1838. In its elemental form, lanthanum has a silvery white appearance. It is a soft, malleable, and ductile metal that oxidizes easily in air. Lanthanum is the first element in the rare earth or lanthanide series. It is the model for all the other trivalent rare earths and it is the second most abundant of the rare earths after cerium. Lanthanum is found in minerals such as monazite and bastnasite. The name lanthanum originates from the Greek word Lanthaneia, which means 'to lie hidden'.
