Solid solutions of 0.65(Bi0.94La0.06)(Fe1-xTix)O3-0.35PbTiO3 (BLFT-PT) for 0.01 ≤ x ≤ 0.06 were fabricated using the mixed oxide method. XRD results indicated that BLFT-PT has a singe perovskite structure and Ti can promote the formation of tetragonal structure. The effects of Ti substitution on dielectric properties of BLFT-PT were studied at frequencies from 102 to 106 Hz over a temperature range...
Single crystals of bismuth ferrite-lead titanate (BFPT) were grown using a flux method. Starting from bismuth ferrite, we added lead titanate, to produce a range of compositions within the BiFeO3-PbTiO3 solid solution, through to the morphotropic phase boundary (MPB). Using a PbO:Bi2O3 flux, and a cooling rate of 0.5°C/h over the temperature range where crystal growth is expected, our aim was to produce...
xBiFeO3-(1-x)PbTiO3 single crystals were grown via a flux method for a range of compositions. Presented here is a study of the domain configuration in the 0.5BiFeO3-0.5PbTiO3 composition using electron backscatter diffraction to demonstrate the ability of the technique to map ferroelastic domain structures at the micron and submicron scale. The micron-scale domains exhibit an angle of approximately...
0.68BiFeO3-0.32PbTiO3 (BFPT) films were prepared on SiO2/Si and Pt/Ti/SiO2/Si substrates by sol-gel method. The XRD patterns of BFPT films show that BFPT films have good crystalline properties, and there are no other peaks of impure phases except for the peaks of BFPT thin film and the substrates. The thickness of BFPT thin films that annealed at 600? for 10 min was about 860 nm when deposited 8 layers...
BiFeO3 -PbTiO3 (BFO-PT) films were synthesized by sol-gel method with the annealing temperatures to be 550degC, 600degC, and 650degC, respectively. The structure and morphology of the films were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The dielectric constant and loss factor are measured. The leakage current density is also performed to check the conductivity...
