High Purity ChunkAmerican Elements specializes in producing high purity Lanthanum Chunks are produced using crystallization, solid state and other ultra high purification processes such as sublimation. Standard Chunk pieces are amorphous uniform pieces ranging in size from 5-15 mm. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into granules, rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. We also produce Lanthanum as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Lanthanum (La) atomic and molecular weight, atomic number and elemental symbol Lanthanum (atomic symbol: La, atomic number: 57) is a Block F, Group 3, Period 6 element with an atomic weight of 138.90547. 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 Bohr Model Lanthanum was first discovered by Carl Mosander in 1838. In its elemental form, lanthanum has a silvery white appearance. Elemental Lanthanum 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'.
