Rhenium Telluride (ReTe) is a crystal grown product generally immediately available in most volumes. Technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Rhenium is a Block D, Group 7, Period 6 element. The number of electrons in each of Rhodium's shells is 2, 8, 18, 32, 13, 2 and its electronic configuration is [Xe] 4f14 5d5 6s2. In its elemental form rhenium's CAS number is 7440-15-5. The rhenium atom has a radius of 137.1.pm and it's Van der Waals radius is 200.pm. The toxicity of Rhenium has not yet been established . Rhenium is the fourth densestelementexceeded only by that of platinum, iridium, and osmium . It has the second highest melting point exceeded only by tungsten and carbon . Rhenium 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. Because of this, thermocouples made of Tungsten/Rhenium alloy is are used when temperatures will rise to 2000 C and rhenium wire is used in photoflash lamps for photography. It is widely used as filaments for mass spectrographs and ion gauges. Rhenium was first discovered by Walter Noddack in 1925 in the Rhine region of Germany. The name Rhenium originates from the Latin word 'Rhenus' meaning "Rhine" after the place of discovery. See Rhenium research below.
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. 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.
