Ammonium Perrhenate (APR) is a colorless powder that dissolves completely in water. At approx. 365 °C it decomposes into rhenium oxide (Re2O7), ammonia (NH3), and water (H2O) as a result of thermal decomposition.

Ammonium perrhenate can be used directly in the production of catalysts, e.g. for synthesizing platinum-rhenium catalysts used to increase the octane rating of gasoline.

In addition, it serves as a precursor material in the manufacture of rhenium metal powder and pellets, an important additive in superalloys. In a homogeneous mixture with the other components of the special alloys, rhenium metal powder is used in semi-finished and finished products, such as anode plates in medical applications.
