dc.descriptionSamples of 0.9Pb(Fe1/2Nb1/2)O3?0.1PbTiO3 were mixed with ZnO at 0, 1, 2, and 3 wt.%, and were synthesised by mixed oxide through a two-step sintering method. Phase transition of the samples was analysed by using X–ray diffractometer (XRD) and Fourier transform infrared spectroscopy (FTIR). The dielectric properties were determined by LCR meter at 1 kHz, 10 kHz, and 100 kHz. The results showed that the morphotropic phase boundary of 0.9PFN?0.1PT shifting to tetragonal phase and suppressed pyrochlore phase when ZnO was added into 0.9PFN?0.1PT. In addition, FTIR spectra peak showed zinc and oxygen bond bonding vibration at frequencies range 3,452 cm?1 and 3,792 cm?1 after level doping ZnO of 3 wt.%. The samples exhibited the maximum dielectric constant at temperature for 144ºC. The dispersion of dielectric constantly decreased with increasing ZnO contents. The relaxor ferroelectric of 0.9PFN?0.1PT ceramic shifted to normal ferroelectric with increasing ZnO contents.
