- •
21 compositions in the system [(PbyBa1−y)(1−3x)La(2x)]TiO3 were synthesized.
- •
An empirical model was developed which predicts lattice constants and tetragonality for P4mm and P4/mmm perovskites.
- •
An empirical model for the unit-cell polarization of A2+B4+O32− perovskites has been derived.
