## Abstract Modulated differential scanning calorimetry (MDSC), thermogravimetric analysis (TGA) and X‐ray diffraction (XRD) were used to study the phase behaviour of NH~4~HSO~4~ (AHS) above room temperature. For powder AHS measured during successive thermal cycles, the MDSC curves show an endother
