High Purity ChunkAmerican Elements specializes in producing high purity Molybdenum Chunk 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 (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. See research below. Molybdenum as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Molybdenum(Mo) atomic and molecular weight, atomic number and elemental symbolMolybdenum is a Block D, Group 6, Period 5 element. The number of electrons in each of Molybdenum's shells is 2, 8, 18, 13, 1 and its electronic configuration is [Kr] 4d5 5s1. In its elemental form molybdenum's CAS number is 7439-98-7. The molybdenum atom has a radius of 136.3.pm and its Van der Waals radius is 200.pm. Molybdenum is toxic unless it is in small quantities. Molybdenum has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum is a catalyst in the oil refining. It has many other applications, including in catalysts, pigments, corrosion inhibitors and lubricants. It has a very high elastic modulus. Molybdenum Bohr Model Massachusetts Institute of Technology (MIT) researchers recently produced complex electronic circuits from Molybdenum Disulfide (MoS2), a material that could help usher in radically new electronic products. Molybdenum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity)Elemental Molybdenum; metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is used in steel alloys to add hardness and raise melting points. It is a component in Hastelloys brand steel. Molybdenum is used in nuclear reactors and aerospace components. The primary commercial source of molybdenum is molybdenite, although it is also recovered as a byproduct of copper and tungsten mining. Molybdenum was first discovered by Carl Wilhelm in 1778. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead. See Molybdenum research below.
