Practically pore‐free Mn‐, Fe‐, and Al‐doped PLZT ceramics were prepared using isostatic hot‐pressing. The incorporation of the dopants in the perovskite lattice of PLZT (Pb 0.9 La 0.1 |Zr 0.5 Ti o.5 O 3+ δ) ceramics was analyzed from measurements of the density, lattice constants, and weight loss during sintering. It was deduced that Mn, Fe, and Al are incorporated as trivalent ions at (Zr, Ti) 4+ sites and that charge compensation is effected by elimination of cation vacancies present in the undoped PLZT.
