Ruthenium (Brittany Lewin)

  1. 1. Ruthenium Watch This: http://www.youtube.com/watch?v=DO SOJNxMU-A The name Ruthenium comes from the Latin word Ruthenia, meaning Russia. Ruthenium was discoveredin 1827 by Gottfried W. Osann(below left) in residues of platinum ore. Karl Klauss isolated the metal in 1844 from the impure oxide and got all the credit.
  2. 2. Osann: Klaus: Ruthenium is a hard white solid Boiling Point: 4150 C
  3. 3. Melting Pont: 2250 C Density: 12.2 g/cm USES: The demand for Ruthenium is rising. It’s used in the electronic industry and chemical industry with smaller amounts being used in alloying. Wear-resistant electrical contact Used to make blades in jet engines Used to make fountain Pens Ruthenium is one of the rarest metals on Earth. It is found in North and South America and in South Africa. ISOTOPES: RU-96, RU-99, RU-94, RU-95, RU-98, RU-100, RU-101, RU-102, RU-116, RU-104, and Ph-105 Extraction:
  4. 4. 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.
