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.

Klaus:
Ruthenium is a hard white solid
Boiling Point: 4150 C

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. 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.
Cost
$30/g
Common Compounds and Uses
