Crystal structure, conductivity, and phase stability of Cs3(H1.5PO4)2 under controlled humidity
Sheel Sanghvi,Sossina M. Haile +1 more
TL;DR: In this paper, a new member of this material class, Cs3(H1.5PO4)2, was studied using a combination of single crystal X-ray diffraction, in-situ powder diffraction and thermogravimetric analysis, and A.C. impedance spectroscopy.

Characteristic features of the change of domain structure in mixed [(NH4)1−x Rbx]3H(SO4)2 crystals in the vicinity of superprotonic phase transition
TL;DR: In this article, the characteristics of the change of the domain structure in the vicinity of the supeprotonic-ferroelastic phase transition in crystals of different compositions are studied and compared with the variations of the crystal structure during the gradual substitution of ammonium by rubidium.

The Influence of Cation Substitution on the Kinetics of Phase Transitions in Crystals of (K,NH4)3H(SO4)2 Solid Solutions
TL;DR: In this article, the thermal and optical properties of (K,NH4)3H(SO4)2 and (K3H,SO4,2)2 single crystals have been investigated and compared in a temperature range of 295-500 K.

EPR studies of phase transitions in (NH4)3H(SO4)2 single crystals
TL;DR: The successive phase transitions reported in triammonium hydrogen disulphate (TAHS) are investigated by EPR using Cu2 and Mn2+ ions as probes in this paper, and the results are consistent with the model that the Cu2 ion occupies the NH4+ (I) position at room temperature, and takes an off-centred position in phase III with an associated electronic dipole moment, responding to the onset of antiferroelectric ordering.
