Résumé : 

Lead zirconate titanate are prepared from an intermediate composition of a binary mixture of PbTiO3and PbZrO3 in the region of coexistence, the morphotropic phase boundary. The mixture of PbO2, TiO2, and ZrO2was characterized using x-ray diffraction. The solid solution CaxPb1-x[(Zr0.53,Ti0.47)0.75Sb0.25]O3 with 0≤x≤0.05 is investigated at the morphotropic phase boundary, where both phases coexist, tetragonal and rhombohedral. The morphology and size of ceramic grains is investigated using scanning electron microscopy and x-ray diffraction
