Properties

Ammonium perbromate is stable at room temperature, and has solubilities which are similar to ammonium perchlorate. Ammonium perbromate is much less hygroscopic in comparison to ammonium perchlorate, and has been shown to increase in weight when maintained in an atmosphere with high humidity.^[2]

Ammonium perbromate begins to decompose at a temperature between 170 and 180 Celsius, and has been observed to explode on occasion.^[2]
