Abstract DTA, structural and electric conductivity investigations were made for (NH4)4H2(SeO4)3 single crystals. A high-temperature phase transition at 378 K to a superionic phase was found. The phase is characterized by a high electrical conductivity (∼4.10−3 Ω−1 cm−1) and a low activation energy (0.11 eV).
