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

Tellurium Bohr ModelTellurium (Te) atomic and molecular weight, atomic number and elemental symbolTellurium (atomic symbol: Te, atomic number: 52) is a Block P, Group 16, Period 5 element with an atomic radius of 127.60. The number of electrons in each of tellurium's shells is 2, 8, 18, 18, 6 and its electron configuration is [Kr] 4d10 5s2 5p4. Tellurium was discovered by Franz Muller von Reichenstein in 1782 and first isolated by Martin Heinrich Klaproth in 1798. In its elemental form, tellurium has a silvery lustrous gray appearance.Elemental Tellurium The tellurium atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Tellurium is most commonly sourced from the anode sludges produced as a byproduct of copper refining. The name Tellurium originates from the Greek word 'Tellus' meaning Earth.
