Samarium (Sm) modified lead titanate ceramics with a composition of (Pb 0.85 Sm 0.1 )(Ti 0.98 Mn 0.02 )O 3 piezoceramics doped with SiO 2 were prepared by conventional mixed-oxide method. Microstructural and compositional analyses of the PbTiO 3 -based ceramics have been carried out using X-ray diffraction (XRD) and scanning electron microscope...
The piezoelectric lead zirconate titanate (PZT)-based ceramics with a composition of Pb 1-0.5x (Zr 0.52 Ti 0.48 ) 1-x Nb x O 3 ; x=0.02-0.06 were prepared by conventional mixed-oxide method, using sintering temperature at 1250 o C and poling field at 0-50 kV/cm. Microstructural...
