Osann(below left) in residues of platinum ore. Karl Klauss isolated the metal in 1844 from the impure oxide and got all the credit. <br />Osann: <br />Klaus: <br />Ruthenium is a hard white solid<br />Boiling Point: 4150 C<br />Melting Pont: 2250 C <br />Density: 12.2 g/cm<br />USES:<br />The demand for Ruthenium is rising. It’s used in the electronic industry and chemical industry with smaller amounts being used in alloying. <br />Wear-resistant electrical contact<br />Used to make blades in jet engines<br />Used to make fountain Pens<br />Ruthenium is one of the rarest metals on Earth. <br />It is found in North and South America and in South Africa. <br />ISOTOPES:<br />RU-96, RU-99, RU-94, RU-95, RU-98, RU-100, RU-101, RU-102, RU-116, RU-104, and Ph-105 <br />Extraction:<br />It is complex to extract because it exists in ores with other metals. The final stage in the chemical process is the hydrogen reduction of ammonium ruthenium chloride. <br />Cost<br />$30/g<br />Common Compounds and Uses<br />Ruthenium and Titanium-To improve titanium’s corrosion resistance<br />Sources:<br />http://education.jlab.org/itselemental/ele044.html<br />http://www.radiochemistry.org/periodictable/elements/44.html<br />www.youtube.com<br />http://www.lenntech.com/periodic/elements/ru.htm<br />
