Ammonium Perrhenate

Rhenium(VI) Oxide Description

Ammonium perrhenate (APR) is the ammonium salt of perrhenic acid, NH4ReO4. It is the most common form in which rhenium is traded.

Ammonium perrhenate (APR) is a colorless powder that dissolves completely in water, ethanol, and mildly soluble in NH4Cl. At approx. 365℃ it decomposes into rhenium oxide (Re2O7), ammonia (NH3), and water (H2O) as a result of thermal decomposition.

Ammonium perrhenate (APR) is used for the direct production of rhenium-based catalysts used in petrochemical refining and as a precursor material for pure rhenium metal powder or pellets.

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.
