Abstract

X-ray-scattering investigation of stoichiometric silver $β$ -alumina reveals a clear phase transition between the high-temperature conducting-ions quasiliquid sublattice, and a lowtemperature crystalline state. Preliminary, structural analysis of the low-temperature crystalline order confirms the type of organization previously deduced for the low-temperature short-range order of nonstoichiometric silver $β$ -alumina.
