Description 711-714
Titanium doped Lithium Germanate (Li4TiGe2O8) is synthesized by ceramic double sintering route. Germanate is sintered at
a temperature of 900o C for 30 min in a microwave furnace. The formation of glass was confirmed by the X-ray diffraction
technique. Electric, dielectric, ferroelectric and piezoelectric properties are investigated. Dielectric studies performed from room
temperature to 500o C showed a steady dielectric constant of approximately 75 throughout the investigated temperature. AC
conductivity of the glass showed very high resistivity of the order of 107 Ω-cm. Further, an ionic hopping conduction
mechanism is suggested from the conductivity behaviour as a function of frequency. Ferroelectric hysteresis recorded at room
temperature has exhibited a square loop suggesting very good ferroelectric nature of the glass. From the obtained high
resistivity and piezoelectric coefficient, the glass can be explored for MMIC and MLCC device fabrication.
