The ferroelectric phase transition in ammonium sulphate
Chemical Physics Letters, 1973Abstract On the basis of the temperature dependence of typical internal modes associated with SO 2− 4 and NH + 4 ions it is inferred that the ferroelectric phase transition near 223°K in ammonium sulphate in primarily due to sudden distortions in the SO 2− 4 ions.

Corrosion Problems of Ammonium Sulphate Manufacture
Anti-Corrosion Methods and Materials, 1954In the manufacture of ammonium sulphate, whether by using evaporators or saturators, the erosive effect of crystals present in solution, the low sulphuric acid concentrations usually present, and the relatively high temperatures of operation give rise to serious corrosion problems which begin at the drawing board stage of design and continue through ...
