STRUCTURAL DIELECTRIC AND ELECTRICAL-PROPERTIES OF LINBMOO6 CERAMICS

Polycrystalline sample of LiNbMoO6 was prepared by high-temperature so lid-state reaction technique. Preliminary X-ray diffraction (XRD) stud ies of the compound suggest the formation of a single-phase compound w ith orthorhombic structure. Detailed studies of dielectric constant (t heta) and loss (tan delta) as a function of frequency (1 to 10 kHz) at room temperature and also as a function of temperature (100 to 600 K) at 10 kHz suggest that LiNbMoO6 has a dielectric anomaly at 369 K. Th e electric field (1.3 to 8.0 kV/m) and temperature (room temperature t o 600 K) variation of de resistivity (phi) show superionic behaviour o f the compound at high temperature region.
