Rhenium is a chemical element in the periodic table that has the symbol Re and atomic number 75. A silvery-white, rare, heavy, polyvalent transition metal, rhenium resembles manganese chemically and is used in some alloys. Rhenium is obtained as a by-product of molybdenum refinement and rhenium-molybdenum alloys are superconducting.

 

This element is used in platinum-rhenium catalysts which in turn are primarily used in making lead-free, high-octane gasoline and in high-temperature superalloys that are used to make jet engine parts.

Rhenium catalysts are very resistant to chemical poisoning, and so are used in certain kinds of hydrogenation reactions. Thermo-couples containing alloys of rhenium and tungsten are used to measure temperatures up to 2200 °C.
