XPS characterization of perovskite relaxor PNN ceramics prepared by corundum precursor method
Perovskite ferroelectric PNN ceramics have been obtained from oxides by sintering in air, using a two-stage process with corundum Ni4Nb 2O9 precursor. Under suitable firing condition, XRD analysis revealed that the ceramics consist of 100% perovskite phase. The SEM, EDX, and XPS techniques were empl...
