The Properties of (Pb0.97Ba0.03)[(Zr0.98Ti0.02)1-zSnz]O3 Ceramics with 0 < z < 0.08

Abstract We present the results of obtaining and investigations of (Pb 1-x Ba x )((Zr 1-y Ti y ) 1-z Sn z )O 3 (PBZTS) ceramics with x =const =0.03, y =const=0.02, z =0, 0.02, 0.04, 0.06 and 0.08. Investigated compositions are close to rhombohedral-orthorhombic morphotropic phase boundary. Ceramic samples have been obtained by conventional ceramic technology from oxides PbO, ZrO 2 , TiO 2 , SnO 2 and barium carbonate BaCO 3 . The calcined powders were crushed and next pressed into discs and sintered free sintering (FS) method. For such obtained samples the following investigations have been done: EDS, XRD, microstructure of fractured samples, dielectric measurements, /’-/^hysteresis loops investigations at various temperatures.
