Application

Ammonium perrhenate is a white, fine crystalline powder utilized primarily for its role in synthesizing rhenium(III) organohydrazides, which have applications as radiopharmaceuticals. Additionally, it is integral in the production of rhenium metal and as an additive in superalloys, enhancing their properties. Its function as a catalyst is particularly notable in the creation of platinum-rhenium catalysts, which are essential in the refinement of gasoline. The core element in these applications is rhenium.
