Scandium Telluride (Sc2Te3) 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.
Scandium is a Block D, Group 3, Period 4 element. The number of electrons in each of Scandium's shells is 2, 8, 9, 2 and its electronic configuration is [Ar] 3d1 4s2. In its elemental form scandium's CAS number is 7440-20-2. The scandium atom has a radius of 160.6.pm and it's Van der Waals radius is 200.pm. Scandium is mildly toxic. Scandium is a metal that has many of the characteristics of the rare earth elements, particularly yttrium. It is a light material with a higher melting point than aluminum giving uses in aerospace and most recently, in racing bicycles and golf clubs. Doping zirconium oxide with scandium oxide produces a low temperature electrolyte in solid oxide fuel cells. Scandium information, including Technical Data, Safety Data and its high purityproperties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Scandium was first discovered by Lars Nilson in 1879. The origin of the name, Scandium, comes from the Latin word 'Scandia' meaning Scandinavia. See Scandium 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..
