(1-x)Bi(Ga,Sc)O3-xPbTiO3 (BGSPT) ceramics were fabricated by using conventional mixed oxide ceramic processing. It was found that the introduction of BiGaO3 into BiScO3-PbTiO3 system would cause a shift of morphotropic phase boundaries (MPB), from x=0.64, y=0 to x=0.58, y=0.115; and an increasing of Curie temperature (Tc) near MPB, from 450¿_C up to 482¿_C,(More)
0.15BiScO3-0.85(Pb1-3x/2Bix)(Ti0.98Mn0.02)O3 (x=0.04~0.10), were prepared by using conventional solid phase processing. The results of X-ray diffraction (XRD) show that the ceramics have a single phase tetragonal perovskite structure. The ceramics, poled by normal poling process, have piezoelectric coefficient d33, planar electromechanical coupling factor(More)
K4CuNb8O23 (KCN) modified (Na0.5K0.5)NbO3 lead free piezoelectric ceramics were synthesized by using oxide powder method. The crystalline structure was characterized by X-ray diffraction (XRD) and with combination of electronic scan microscopy (SEM). Dielectric constant dependence of temperature at different frequency and piezo-, ferroelectric properties(More)
