Characteristic

 

Ammonium perrhenate (APR) is the ammonium salt of perrhenic acid, NH4ReO4. It is the most common form in which rhenium is traded. It is a white, water-soluble salt. It was first described soon after the discovery of rhenium.




Chemical formula:NH4ReO4

Molar mass:268.2359 g/mol

Density:3.97 g/cm3, solid

Solubility in water:2.8 g/100 mL (0 °C), 6.2 g/100 mL (20 °C), 12.0 g/100 mL (40 °C), 20.7 g/100 mL (60 °C), 32.3 g/100 mL (80 °C), 39.1 g/100 mL (90 °C)

 


Application

 

Ammonium perrhenate(VII) is used to synthesis the rehenium(III) organohydrazides which is used as radiopharmaceuticals and also used in the manufacturing of rhenium metal and its additives in superalloys. It is used as catalyst for the synthesis of platinum-rhenium catalysts which used in gasoline.
