Abstract

Relaxor ferroelectric-based complex perovskite 0.91Pb(Zn_1/3Nb_2/3)O₃-0.09PbTiO₃ [PZNT91/9] and 0.68Pb(Mg_1/3Nb_2/3)O₃-0.32PbTiO₃ [PMNT68/32] single crystals were grown by a modified Bridgman process and by the flux technique. Their thermal properties were measured by simultaneous microdifferential thermal analysis (DTA) and thermogravimetric analysis (TGA), combined with phase analysis based on X-ray powder diffraction patterns of thermally treated samples. Upon heating at atmospheric pressure, the perovskite PZNT91/9 crystals undergo successively a decomposition at 1148°C and a peritectic melting at 1226°C with the formation of a pyrochlore phase. A liquidus point was found at 1268°C. The PMNT 68/32 crystals show a sharp peritectic melting at 1270°C and a liquidus point at 1288°C. The results on the melting behavior and phase stability of the morphotropic PZNT and PMNT crystals provide valuable data for guiding the crystal growth process.
