Dielectric and Electrical Studies of SrBi2Nb1.9V0.1O9 Ferroelectric Ceramics
In the present work, effect of sintering temperature on structural, dielectric and electrical properties of vanadium substituted strontium bismuth niobate ferroelectric ceramics have been studied. Samples of composition SrBi2Nb1.9V0.1O9 were synthesized by solid-state reaction method at different sintering temperatures. X –ray diffraction analysis reveals the formation of perovskite structure. Peak dielectric constant is found to increase with increasing sintering temperature while Curie temperature is observed to be the highest in the sample sintered at 900 oC and it decreases in the sample sintered at 1000 oC. Impedance analysis of the samples was carried out to study the grain and the grain boundary effects. Cole-cole plots reveal a decrease in bulk resistance on increasing temperature indicating NTCR behavior.
