About

Telluride IonBismuth Telluride is a narrow gap layered semiconductor with high thermal conductivity. Recent research has confirmed that bismuth telluride may significantly increase the speed of microchips and be the basis for the emerging next generation technology know as "Spintronics". American Elements Bismuth Telluride products are generally available in most volumes and can be purchased in bulk quantites. American Elements can produce most materials in high purity and ultra high purity (up to 99.99999%) forms and follows applicable ASTM testing standards; a range of grades are available including Mil Spec (military grade), ACS, Reagent and Technical Grade, Food, Agricultural and Pharmaceutical Grade, Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia). We can also produce materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies. Typical and custom packaging is available, as is additional research, technical and safety (MSDS) data. Please contact us above for information on specifications, lead time and pricing.

See more Bismuth products. Bismuth (atomic symbol: Bi, atomic number: 83) is a Block P, Group 15, Period 6 element with an atomic radius of 208.98040. The number of electrons in each of Bismuth's shells is 2, 8, 18, 32, 18, 5 and its electron configuration is [Xe] 4f14 5d10 6s2 6p3. Bismuth Bohr ModelThe bismuth atom has a radius of 156 pm and a Van der Waals radius of 207 pm. In its elemental form, bismuth is a silvery white brittle metal. Bismuth is the most diamagnetic of all metals and, with the exception of mercury, its thermal conductivity is lower than any other metal. Elemental BismuthBismuth has a high electrical resistance, and has the highest Hall Effect of any metal (i.e., greatest increase in electrical resistance when placed in a magnetic field). Bismuth is found in bismuthinite and bismite It is also produced as a byproduct of lead, copper, tin, molybdenum and tungsten extraction. Bismuth was first discovered by Early Man. The name Bismuth originates from the German word 'wissmuth,' meaning white mass.

See more Tellurium products. Tellurium (atomic symbol: Te, atomic number: 52) is a Block P, Group 16, Period 5 element with an atomic radius of 127.60. Tellurium Bohr ModelThe 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. The tellurium atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Elemental TelluriumTellurium 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.
