Rhenium (Re) is a silvery-gray, heavy, transition metal. The major application of rhenium is as an alloying element in Nickel-based superalloys used in combustion chambers, turbine blades, and exhaust nozzles of jet engines. The second-most important use is as a catalyst: rhenium is an excellent catalyst for hydrogenation and isomerization, and is used for example in catalytic reforming of naphtha for use in gasoline. Due to its high value, it is usually used as a coating material in catalyst application.
