Abstract

Analysis of the EPR of SO^-₄ centers in LiKSO₄ crystals indicates that the SO^-₄ centers are associated with local positive-ion vacancies. Twin-domains of the 〉110〈 types are observed to be temperature-dependent. The anomaly at 215 K on cooling is associated with a sudden growth of the twins and the anomaly at 190 K is associated with a p6₃ to p6₃P6,mc structural phase transition.
