Structural, Dielectric And Ferroelectric Properties Of Y3+ Doped PZT (65/35)

Yttrium doped lead zirconium titanate (PYZT) was prepared by chemical co-precipitation technique using their nitrate salts. X-ray diffraction analysis was carried out to confirm the phase formation and to study the structural changes with Y doping in PZT. Scanning electron micrographs of the sample show uniform grain distribution with decreasing grain size with Y doping. The dielectric maxima was found to be enormously increased from 1791 to 2687 along with decreasing phase transition temperature from 335 to 400 o C with Y doping in PZT. The remnant polarization was also found to increase from ~11 to ~44 μC/cm 2 with Y doping.
