From binary PZT system to multi-component ferroactive materials

Abstract

For the first time, ceramic solid solutions of the five-component system 1-x)(0.5(Na0.5K0.5)NbO3–0.5Pb(Zr0.5Ti0.5)O3)-x/2CdNb2O6 with concentrations of CdNb2O6x = 0.000; 0.025; 0.050; 0.075 were prepared. Experimental studies of crystalline and grain structure, dielectric, piezoelectric and ferroelastic properties have been carried out over a wide temperature range. X-ray diffraction data were used to construct a concentration diagram of the phase states and to establish correlations between the behaviour of the macroproperties of the solid solutions and the features of their crystal structure. A conclusion is made about the expediency of using the obtained results in the creation of similar materials and devices based on them.
