Аннотация: Triclinic NASICON-type hafnium hydrogen phosphate HHf₂(PO₄)₃·0.5H₂O was obtained by ion exchange from LiHf₂(PO₄)₃. The dehydration of HHf₂(PO₄)₃·0.5H₂O (∼ 400 K) followed by a triclinic-rhombohedral phase transition (∼470 K) was observed, and the resulting HHf₂(PO₄)₃ was stable up to 870 K. The proton conductivity of the sample was 4.7×10^–7 Ohm^–1 cm^–1 at 773 K.
