| Summary: | 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 0C and for both BLT and BNT better result obtained at 800
0C. 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 0C and La and Nd
co-doped bismuth titanate (BLNT) revealed optimum sintering temperature of
950 0C. Therefore, optimum sintering temperature of bismuth titanate was
increased due to La and Nd doping. |
