Dielectric And Piezoelectric Properties

The behaviour of the dielectric and piezoelectric properties of doped PZT ceramics, with variable lead content, has been investigated from –50oC to room temperature. The PZT materials were prepared by the oxide technique and samples were sintered as pellets, at various temperatures. Niobium and lithium ions have been substituted for Ti4+, Zr4+ in the PZT matrix, and a small amount of Bi2O3 was added to cause A-position vacancies. The lead content in the four materials prepared varies in a narrow range, from 0.97 to 1.029 lead atoms, while the concentration of all other components are maintained constant. The microstructure of samples, evaluated by SEM technique and XRD analysis evidenced the presence of the tetragonal phase characteristic for the PZT 52/48. The dielectric and piezoelectric c onstants measured on poled samples depends on the sintering temperature, defects and domain walls, lead content.

The microstructure, physical, dielectric and the piezoelectric characteristics of the (K0.5Na0.5) (Nb0.9Ta0.1) O3 (KNNT) ceramics as a function of the sintering temperature and Nd2O3 dopant were inspected in this work. It was found that the sintering temperature has a significant impact on the above-mentioned properties. In the same context, the addition of HYPERLINK "https://pubchem.ncbi.nlm.nih.gov/compound/Neodymium_oxide" neodymium oxide led to remarkable improvement in the microstructure, density, dielectric and piezoelectric properties of KNNT ceramics when compared to undoped ceramics.

La-modified PZN-PZT compositions with representative formula Pb1-0.7xLa0.7x(Zn1/3Nb2/3)0.3- (Zr0.55Ti0.45)0.7(1-x/4)O3 were prepared by the columbite precursor method. La content, x, was varied from 0 to 8mol%. Effects of La doping on microstructure, dielectric and piezoelectric properties were investigated. The results showed that in present system La doping promotes the formation of pyrochlore phase and the phase shifted from rhombohedral to tetragonal structure with increasing La content. It was also found that La doping makes dielectric permittivity maximum decrease and the degree of diffuse phase transition enhance. Appropriate amount of La doping could improve the piezoelectric properties.
