Notes:
Bi4-xLaxTi3O12 (BLT, x=0, 0.75, 1, 2) ceramic powders were prepared with sol-gel and solidphase reaction processes, respectively. BLT powders were synthesized after decarbonization at 300ºC for1h followed by calcination at 800ºC for 2h. The ceramics synthesized with cold isostatic pressing andsintering at 1150ºC exhibit a perovskite-like structure. The influence of sintering parameters and Ladoping content on density, microstructure and dielectric properties of the BLT were discussed. With theincrease of La doping content in Bi4-xLaxTi3O12, dielectric constant increases and dielectric loss graduallydecreases. The dielectric constant and dielectric loss of Bi4-xLaxTi3O12 (x=2) are 132.7 and 0.012 at 100KHz, respectively
