This study describes structure, dielectric and piezoelectric properties of Pb[(Zr0.45,Ti0.5)(Mn0.5,Sb0.5)0.05]O3 (PZT-PMS) ceramics prepared by conventional mixed-oxide route and sintered at up to 1180 °C. The prepared ceramics was characterized by X-ray diffraction and scanning electron microscopy. The piezoelectric constants, dielectric constant, Young’s modulus and electromechanical factors were measured in broad temperature range. The results showed that the PZT-PMS ceramics is composed of tetragonal and rhombohedral phases and has the average grain size of about 1 µm. The Pb[(Zr0.45,Ti0.5)(Mn0.5,Sb0.5)0.05]O3 ceramics has excellent dielectric and piezoelectric properties for wide practical applications. Thus, planar coupling factor of 0.70, poled dielectric constant of 8215, the Curie temperature of 345 °C and dielectric loss of 6% were attained in the PZT-PMS ceramics sintered at 1180 °C.
