摘要：
A good understanding about the properties of La/Nd doped Bismuth Titanate (BIT) ceramics at high temperature is very important as the new materials being developed based on the BIT. Pure BIT, La doped (BLT), Nd doped (BNT) and La and Nd co-doped BIT (BLNT) powders were synthesized by solid state reaction method. Prepared powders were calcined at different temperatures and structural properties measured by XRD. For pure BIT better crystal quality was obtained at 750 degrees C and for both BLT and BNT better result obtained at 800 degrees C. Calcined powders were formed into pellets and sintered at different temperatures and its dielectric properties were characterized. Optimum sintering temperature for both BLT and BNT showed was 850 degrees C and La and Nd co-doped bismuth titanate (BLNT) revealed optimum sintering temperature of 950 degrees C. Therefore, optimum sintering temperature of bismuth titanate was increased due to La and Nd doping.
