Abstract

Characterization and synthesize of Ba_1-xCe_xTiO₃ (x=0.01mol.) annealed at three different temperatures (1100^oC, 1200 ^oC, 1300 ^oC) have been studied. For preparing powder of (x = 0.01 moles), Sol- Gel synthesis was carried out according to the stoichiometric conditions. The powder obtained palletized at 1.5 ton /mm² pressure into a 10 mm dia. Pellet using PVA (polyvinyl alcohol) as binder. The pellets were then annealed at 1100^oC for 1 hour. Then silver paste was applied on pellet by fully coating the one side and applying a single dot on other side, for making the pellet as capacitor. The XRD pattern reveals that the lattice parameter increases with the Ce doping and c/a ratio decreased which shows that tetragonality decreases. In all investigated samples it is assumed that the phase transition analysis, after doping Ce in BaTiO₃ the Curie temperature decreases.
