Rhenium

About Rhenium (Re)

Symbol: Re
Atomic number: 75
Atomic mass: 186.207
Element category: Transition metal

Rhenium is one of the rarest stable elements on Earth. It exhibits a melting point of 3 186 °C, which is the third highest among all elements, exceeded only by tungsten and carbon. It is chemically inert, maintains stability at high temperatures, has a high density and retains mechanical strength at elevated temperatures.

In industry, rhenium is used primarily in superalloys, particularly in aerospace applications for turbine blades or jet engines. It is also a component in platinum–rhenium catalysts that are employed in the reforming of hydrocarbons such as olefins.

Rhenium can occur in oxidation states ranging from –1 to +7. Of technical relevance are perrhenate salts such as sodium perrhenate or ammonium perrhenate, which find use in various catalytic processes.
