A new high-temperature ferroelectric ternary solid solution xBi(Mg 1/2Ti1/2)O3-yBi(Zn1/2Ti 1/2)O3-zPbTiO3 has been developed and characterized. A detailed study on the preparation and characterization of the compositions along the pseudobinary line xPT-(1-x)(0.9BMT-0.1BZT) has been performed to study the property trends with composition. High c/a ratio of 1.04 has been observed for the composition with surprisingly low tolerance factor of 0.97. These compositions have been studied with focus mainly on the tetragonal phase field. Varied transition temperature trends have been observed along the pseudobinary line, which is then compared with the individual binary BZT-PT and BMT-PT systems. Structure property relationship is evaluated and discussed in terms of modern ferroelectric theories.
