Tarix
In 1908, Japanese chemist Masataka Ogawa announced that he discovered the 43rd element.
However, later analysis indicated the presence of rhenium (element 75), not element 43.
In 1922, Walter Noddack, Ida Eva Tacke and Otto Berg announced its separation from gadolinite and gave it the present name.

Applications
Rhenium is widely used as filaments for mass spectrographs and ion gauges.
It is also used with platinum as catalysts in the production of lead-free, high-octane gasoline.
Nickel-based superalloys of rhenium are used in the combustion chambers, turbine blades, and exhaust nozzles of jet engines.
