Structural and morphological characterization of rare earth modified lead titanate Caracterização estrutural e morfológica de titanatos de chumbo modificados por terras raras

Rare earth modified lead titanate powders Pb1-xRExTiO3 (REPT), x = 0.01, 0.05, 0.07 and RE = Yb, Y, were prepared by the Pechini method. The materials were calcined under flowing oxygen at different temperatures from 300 to 700 ºC. Nanostructured REPT were investigated using X-ray diffraction, scann...
