The -phase of SrTeO₃ at 583 K

V. E. Zavodnik, S. A. Ivanov and A. I. Stash

Abstract: As a part of current systematic investigations of strontium tellurite, SrTeO₃, with particular emphasis on crystal chemistry and phase transitions, the structure of the phase has been determined at 583 K using a single-crystal analysis. Both structural and nonlinear optical measurements indicate a - first-order phase transition temperature that is close to 563 K. The structure of the phase is monoclinic (C2) and does not differ essentially from the phase (C2). Comparison of the and structures shows that the main atomic shifts and tiltings are connected with Te4, Te5 and Te6 pyramids.
