Abstract
The formation of a complete series of solid solutions in the system PbTiO3-KNbO3 was established by X-ray and dielectric studies. The room-temperature symmetry of the entire system was tetragonal except for compositions containing more than 96 mole % KNbO3, which had orthorhombic symmetry. The axial ratio, c/a, and the ferroelectric Curie temperature decreased from both the end-members. The lowest Curie temperature observed in the system was 175° C for the composition with 80 mole % KNbO3. A generalization has been made on the variation of ferroelectric Curie temperatures with compositions in binary systems of perovskitetype solid solutions with and without a common cation.
