Abstract :

Lead ceramics Pb[(Zrx, Ti(1-x))0.9 (Cr1/5, Nb1/5, Sb3/5)0.1]O3 with varying Zr/Ti ratio (0.46 â?¤ x â?¤ 0.51), prepared by conventional solidstate reaction method and their structure, electrical and piezoelectric properties were systematically investigated. X-ray diffraction analysis revealed that the morphotropic phase boundary (MPB) of PZT-PCNS ceramics located near (0.47 â?¤ x â?¤ 0.49), confirmed by their corresponding dielectric and piezoelectric properties. Scanning electron microscopy indicated that increasing x from 0.46 to 0.51 causes an increase in the grain size. The Pb[(Zrx, Ti(1-x))0.9 (Cr1/5, Nb1/5, Sb3/5)0.1]O3 ceramics show a homogeneous microstructure and excellent dielectric and piezoelectric properties. Specimens with optimum composition showed a piezoelectric charge constant d31 of 166pC/N, an electromechanical coupling factor kp of 0.5 and dielectric constant ?µr of 1591.32 at 1kHz.
