| Abstract |
| The Pb4/5Sr1/5 (Zr11/20Ti9/20)O3
-Pb(Mn1/3Sb2/3)O3
-Pb(W1/3Nb2/3)O3
(PSZT-PMS-PWN)
ceramics were prepared via the solid-state reaction method. The effect of sintering
temperatures on PSZT-PMS-PWN phase formation, microstructure and electrical
properties were investigated. The X-ray diffraction study confirmed pure perovskite
structure formation in the prepared ceramics and the coexistence of rhombohedral
and tetragonal phases has been detected in all ceramics at room temperature.
Scanning electron micrographs of fractured PSZT-PMS-PWN ceramics revealed
equiaxed grains and the presence of both transgranular and intergranular fracture
modes. Optimal electrical properties were obtained at a sintering temperature of
1175oC, characterized by a high dielectric constant (r=12735), a Curie temperature
(TC) of 630 K, a dielectric loss (tan) of 0.03, a piezoelectric charge constant (d33) of
341 pC/N, an electromechanical coupling factor (KP) of 0.624, and a mechanical quality
factor (Qm) of 1260. These properties indicate strong potential for applications in
piezoelectric-related fields, especially under demanding or extreme conditions. |
