Abstract

Lanthanum and calcium modified barium titanate, Ba_(1-x)La _xTi_(1-x/4)O₃/BLT and Ba(_1-x)Ca _xTiO₃/BCT, where x=0.02, ferroelectric ceramic samples were synthesized in single perovskite phase by microwave processing technique. Sintering temperature was optimized at 1100°C for 1h. Presence of pore free micron size uniform grains suggested the advantage of using microwave sintering process. Transition temperature (T_c) decreases with the substitution of La content in BT system. Temperature coefficient of capacitance is negligible from RT temperature to 75°C for BLT ceramic samples. Polarization vs. electric field (P-E) hysteresis loop study confirms the ferroelectric nature of the modified BT ceramic samples.
