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

Ruthenium(Ru) atomic and molecular weight, atomic number and elemental symbolRuthenium is a Block D, Group 8, Period 5 element. The number of electrons in each of Ruthenium's shells is 2, 8, 18, 15, 1 and its electronic configuration is [Kr] 4d7 5s1. In its elemental form ruthenium's CAS number is 7440-18-8. The ruthenium atom has a radius of 132.5.pm and its Van der Waals radius is 200.pm. Ruthenium tetroxide (RuO4) is very toxic and Ruthenium in its elemental form is considered carcinogen. Ruthenium is a member of the platinum group of metals. It is one of the most effective hardeners for platinum and palladium, and is alloyed with these metals to make electrical contacts for severe wear resistanant Elemental Rutheniumelectronics and laboratory equipment. The corrosion resistance of titanium is improved a hundredfold by addition of 0.1% ruthenium. It is also a versatile catalyst. Hydrogen sulfide can be split catalytically by light using an aqueous suspension of cadmium sulfide particles loaded with ruthenium dioxide.Ruthenium Bohr Model Building on their prior experimentation with ruthenium compounds, in January 2013 scientists at the Pacific Northwest National Laboratory sucessfully demonstrated a novel and efficient method of moving protons, a mechanism key to finding ways to generate and store the energy produced by solar and other green technologies. Ruthenium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Ruthenium is found in pentlandite, pyroxenite, and platinum group metal ores. Ruthenium was first discovered by Karl Klaus in 1844. The name Ruthenium, originates from the Latin word 'Ruthenia' meaning Russia. See Ruthenium research below.
