Ruthenium Telluride (RuTe2) 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.
Ruthenium is a Block D, Group 8, Period 5 element. The number of electrons in each of Ruthenium's shells is 2, 8, 18, 15, 1 and its electronic configuration is [Kr] 4d7 5s1. In its elemental form ruthenium's CAS number is 7440-18-8. The ruthenium atom has a radius of 132.5.pm and it's Van der Waals radius is 200.pm. Ruthenium tetroxide (RuO4) is very toxic and Ruthenium in its elemental form is considered carcinogen. Ruthenium is member of the platinum group of metals. It is one of the most effective hardeners for platinum and palladium , and is alloyed with these metals to make electrical contacts for severe wear resistanant electronics and laboratory equipment. The corrosion resistance of titanium is improved a hundredfold by addition of 0.1% ruthenium. It is also a versatile catalyst. Hydrogensulfide can be split catalytically by light using an aqueous suspension of cadmiumsulfide particles loaded with ruthenium dioxide. It is also believed to have pharmacological applications. Ruthenium 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. Ruthenium was first discovered by Karl Klaus in 1844. The name Ruthenium, originates from the Latin word 'Ruthenia' meaning Russia. See Ruthenium 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.
