Abstract

A series of Ce-doped BaTi0.97Y0.03O3 powder samples with the composition (Ba1-xCex)(Ti(0.97-x/4)Y0.03)O3 (x = 0.00, 0.01, 0.03, 0.05, 0.07 and 0.09) were prepared using the sol gel process and calcined at a relatively low temperature (950°C/4h) and their structural and piezoelectric properties investigated. From structural investigations, it was observed that the samples crystallize in the pseudo cubic phase with the presence of secondary phases for concentrations such as x > 0.03. Piezoelectric parameters were determined and their thermal behavior investigated. The impedance study indicated the dominance of the resistance of the grain boundaries compared to that of grains in BaTi0.97Y0.03O3 sample.
