Bhowmick, Luna (2012) Synthesis and characterization of La doped
Bi4Ti3O12 ceramics.
MSc thesis.



Bi3.25La0.75Ti3O12 (BLT) was prepared by the conventional solid state route as well as the chemical route. Calcination of the sample prepared through the solid state route was done at 7500C for 4 hours and of the sample prepared through the chemical route at 6000C for 4 hours. XRD of the samples was done in which BLT layered perovskite phase was confirmed. The samples were sintered using the conventional sintering method at 11500C for
4 hours and that of the sample prepared by chemical route was done at 11500C for 2 hours. Density measurement was done to confirm final densification after sintering. SEM images of the samples were taken which showed dense microstructure and uniform grain size. Comparative study of dielectric properties of the samples prepared by both solid state and chemical route were performed. PE loop measurements were done to confirm the ferroelectric nature of the sample.
