| Abstract: | Beside the transition into a ferroelectric phase at 583 K, monoclinic SrTeO3(I) at ?1260 K transforms slowly into a high-temperature form (SrTeO3(II)) which after quenching undergoes rapid phase transitions at 648 and 733 K. X-Ray data of triclinic α-SrTeO3(II) (room temperature), monoclinic β-SrTeO3(II) (660 K), and monoclinic γ-SrTeO3(II) (770 K) are presented. |
