Structure, morphology, and ferroelectric behavior of Ba1-yZnyTiO3 (y = 0.2, 0.4, 0.6 & 0.8) nanoceramics

The barium zinc titanate (BZT) nanoceramic samples were prepared via the hydrothermal technique. It was found from XRD patterns that the y = 0.2 to 0.8 compositions showed the cubic perovskite structure along with some secondary phases related to the zinc titanate (Zn2TiO4). The surface morphology indicated the formation of nanospheres like grains/particles for y = 0.2, and 0.3 compositions while the rest of the samples showed the rods like structures. Further the P-E loops of y = 0.2-0.8 samples showed the saturation of all samples.
