Mohapatra, Chinmaya (2011) Synthesis and Characterization of Ferroelectric ceramic by soft chemical route. MSc thesis.
The single phase ceramic powder with general formula Ba1-xSrxTiO3 ceramic is prepared by soft chemical route. The structural analysis was done by XRD. The well defined crystalline XRD pattern was observed with single phase. Upto x=0.1 it is showing tetragonal structure and for higher doping it shows cubic structure. The morphological study was done by SEM which shows that the grain size if effected by the substitution level. The temperature and frequency dependency dielectric study was done. It shows that the dielectric constant at room temperature first increases upto x=0.3 and then decreases for the higher composition. The temperature dependency dielectric study of x=0.0 show a normal ferroelectric behaviour. The ferroelectric behaviour is again confirmed by the P-E loop study.
