Ammonium Hexabromotellurate(IV) is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.American Elements produces to many standard grades when applicable, 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)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Tellurium is a Block P, Group 16, Period 5 element. The number of electrons in each of Tellurium's shells is 2, 8, 18, 18, 6 and its electronic configuration is [Kr] 4d10 5s2 5p4. In its elemental form tellurium's CAS number is 13494-80-9. Tellurium is very toxic and can cause birth defects. The tellurium atom has a radius of 143.2.pm and it's Van der Waals radius is 206.pm. Tellurium is a p-type semiconductor, and shows greater conductivity in certain directions, depending on alignment of the atoms. It is grown in crystalline form with other elements such as indium telluride. Its conductivity increases slightly with exposure to light which makes many tellurides candidates for solar energyapplications. Tellurium improves the machinability of copper and stainless steel, and its addition to lead decreases the corrosive action of sulfuric acid on lead and improves its strength and hardness. Tellurium is used as a basic ingredient in blasting caps, and is added to cast iron for chill control. Tellurium is used in ceramics. Bismuth telluride has been used in thermoelectric devices. Iron 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. Tellurium was first discovered by Franz Muller von Reichenstein in 1782. The name Tellurium originates from the Greek word 'Tellus' meaning Earth. See Tellurium research below.
