A Wisdom Archive on ruthenium

This element is generally found in ores with the other platinum group metals in the Ural Mountains and in North and South America. Small but commercially important quantities are also found in pentlandite extracted from Sudbury, Ontario and in Pyroxenite deposits in South Africa. This metal is commercially isolated through a complex chemical process in which hydrogen is used to reduce ammonium ruthenium chloride yielding a powder. The powder is then consolidated by powder metall ...

Due to its highly effective ability to harden platinum and palladium, ruthenium is used in Pt and Pd alloys to make severe wear resistance electrical contacts. 0.1% ruthenium is added to titanium to improve its corrosion resistance a hundredfold. Ruthenium is also a versatile catalyst: Hydrogen sulfide can be split by light by using an aqueous suspension of CdS particles loaded with ruthenium dioxide. This may be useful in the removal of H2S from oil refin ...

To help compare different orders of magnitude this page lists lengths between 10−10 m and 10−9 m (100 pm and 1 nm). Lengths shorter than 100 pm 100 pm = 1 Ångström 100 pm — covalent radius of sulfur atom 126 pm — covalent radius of ruthenium atom 135 pm — covalent radius of technetium atom 153 pm — covalent radius of silver atom 154 pm — mode length of (C-C) covalent bond 155 pm — covalent radius of zirconium atom < ...
