Rhenium

About Rhenium

Rhenium is one of the rarest elements in the Earth's crust, produced exclusively as a byproduct of molybdenum and copper mining. It is essential for single-crystal superalloys used in jet engine turbine blades, where it enables operation at extreme temperatures. Rhenium is also a critical catalyst in petroleum refining for producing high-octane, lead-free gasoline.
