Abstract Electron diffraction, high-resolution transmission electron microscopy and scanning transmission electron microscopy reveal that Ti n O2n−1 Magnéli phases, Ti4O7, Ti5O9 and others, exist at the multiple grain junctions in strontium titanate dielectrics. A new type of ledge structure detected at coherent grain boundaries in the Ti4O7 phase is characterized in detail. The SrTiO3 grain and the second phase maintains a particular orientation relationship. Epitaxial growth of Ti4O7 from the silica-rich liquid phase occurs during cooling; the crystal growth geometry of Ti4O7 is related to the directly observed atomically rough interface and atomically smooth interface.
