High Purity ChunkAmerican Elements specializes in producing high purity Manganese 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. We also produce Manganese as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Manganese(Mn) atomic and molecular weight, atomic number and elemental symbolManganese is a Block D, Group 7, Period 4 element. The number of electrons in each of Manganese's shells is 2, 8, 13, 2 and its electronic configuration is [Ar] 3d5 4s2. In its elemental form manganese's CAS number is 7439-96-5. The manganese atom has a radius of 136.7.pm and its Van der Waals radius is 200.pm. Manganese in excess is toxic, in particular the inhalation of manganese in powder or dust form. Manganese metal is a key component of aluminum alloys. Manganese oxide is used in dry cellManganese Bohr Model batteries. Manganese is used in steel production to remove sulfur and oxygen. Manganese is the colorant in natural amethyst stones and is used in glass and ceramics to also create the amethyst color. It is used like the element cerium to "decolorize" glass by offsetting the green from impurities of ferric ions. Permanganate is a powerful oxidizing agent and is used in medicine. Elemental Manganese It is added as a nutritional supplement for both human and animal consumption. Recently, the oxide in the form of various perovskite structures have demonstrated applications in oxygen generation and solid oxide fuel cells. Researchers at Japan's Riken Advanced Science Institute recently discovered a more energy efficient magnet comprised of Bismuth, Telluride, and Manganese. The magnets are part of a newly discovered class of magnetic material known as topological insulators. Manganese was first discovered by Johann Gahn in 1774. Manganese is found in pyrolusite MnO2, braunite (Mn2+Mn3+6)(SiO12), psilomelane (Ba,H2O)2Mn5O10 and rhodochrosite MnCO3. The name Manganese originates from the Latin word mangnes meaning magnet. See Manganese research below.
