Ruthenium Facts
Ruthenium (Ru) has an atomic number of forty-four. It is a hard, white element that is a member of the platinum metals group.
Interesting Ruthenium Facts:
In 1844, Karl Ernst Claus discovered ruthenium in the platinum remainder of rouble production.
It is a transition metal, and is considered very rare.
Only around twenty tons of ruthenium are produced annually.
Ruthenium is sometimes used in platinum alloys.
Its most common purpose is for creating a coating of wear-resistance.
When it is added to titanium, ruthenium causes a corrosion-resistant property.
It is also a superconductor below ten degrees Kelvin when alloyed with molybdenum.
Ruthenium is the only group 8 element to not have two electrons in its outer shell.
Ruthenium does not tarnish under normal temperature conditions.
There are seven natural, stable isotopes of ruthenium.
There are also thirty-four radioisotopes.
The most stable of ruthenium's radioactive isotopes has a half-life of only 373 days.
Most of ruthenium's other radioisotopes have half-lives of less than five minutes.
Ruthenium is the seventy-fourth most common metal on Earth.
Ruthenium is typically mined from ores of other platinum group metals, and most often from the mineral pentlandite.
Only about twelve tons of ruthenium is extracted annually.
The percentage of ruthenium in the platinum ores that are mined varies greatly depending on the global location of the mine.
Like other members of the platinum group, ruthenium is also a result of the mining of copper and nickel.
Noble metals and platinum group metals like ruthenium gather at the bottom of the container during the electrorefining of both nickel and copper.
This material is known as anode mud, and can be a source of ruthenium.
Ruthenium can also be extracted from nuclear waste such as uranium-235.
Ruthenium is being researched for its possible applications in solar energy technology.
It is also being studied for its potential in creating a magnetoresistant component of computer hard drives.
