Rhenium

Rhenium

History

Rhenium was discovered in 1925 spouses Noddak and their Assistant Bergen. The first metallic rhenium was obtained in 1928. In 1955 in England began adding rhenium to molybdenum and tungsten, which increases their strength and ductility.

Nowadays

Rhenium has been an important material for electronic and electrical industry. It is here that the most used set of remarkable properties of the metal and its alloys. Of those, make the filament, grid heaters cathodes. Details of the rhenium alloys is in cathode ray tubes, receiving and amplifying and generating lamps in thermionic generators in mass spectrometers and other precision instruments.
