Preparation and Properties of PSZTM Ceramics with Different Methods

Abstract

The PSZTM ceramics from Pb0.94Sr0.06(Zr0.52Ti0.48)O3doped with 0.1 mol% Mn were prepared by a solid state reaction and. Two different methods were used to calculate the amount of Mn-dopant into PSZT powder. One was calculated rely on B-site precursor represented byBmethod. The other was computed based on the amount of calcined PSZT calledCmethod. This study was to investigate the effect of the two different calculating formulations of Mn doped PSZT ceramics by B and C methods on phase formation, microstructure, physical and electrical properties. The results were observed that phase identification showed the formation of perovskite structure in both cases. Besides, the mechanical quality factor (Qm) of the PSZTM ceramics derived fromBmethod was two times higher than those fromCmethod. Nevertheless, the dielectric constant (K), piezoelectric coefficient (d33) and planar coupling coefficient (kp) of the PSZTM ceramics fromBmethod were slightly lower than those of derived fromCmethod. This could be drawn the conclusion that PSZTM with 0.1 mol% Mn prepared byBmethod can be used as hard-type piezoelectric material.
