Rhenium (Lat. Rhenium) is an extremely strong metal with a high level of resistance to wear and corrosion. Rhenium has the third-highest melting point of all chemical elements (after tungsten and carbon) – 3185 °C – and a boiling point of 5590 °C. This metal is a good conductor of heat and electricity and one of the rarest chemical elements in the Earth’s crust. Rhenium is one of the most expensive metals used in industry.
Rhenium (chemical symbol Re) is often used to make highly heat-resistant metal alloys – according to the USGS, about 80 per cent of rhenium is consumed for them. Alloys of this element are used to manufacture aircraft turbine blades and rocket combustion chambers. About 15 per cent of rhenium is used in oil-refining catalysts.
One of the more expensive metals on Earth is relatively rarely found in everyday life. Rhenium is used in the manufacture of some electronic device components, such as electrical contacts, heating elements and thermocouples. However, the amounts in electronic devices are absolutely minimal.
