The Properties Of (Pb0.97ba0.03)[(Zr0.98ti0.02)(1-Z)Sn-Z]O-3 Ceramics With 0 < Z < 0.08

We present the results of obtaining and investigations of (Pb1-xBax)((Zr1-yTiy)(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, ZrO2, TiO2, SnO2 and barium carbonate BaCO3. 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, P-Ehysteresis loops investigations at various temperatures.
