| Abstract: | The laws of formation of an equilibrium crystalline structure of lead titanate during crystallization from an amorphous state were studied. The initial thermal treatment leads to structural relaxation of the amorphous state. Subsequently, an intermediate state is formed whereby cubic phases with perovskite and pyrochlore structures coexist in the amorphous matrix. Finally, an equilibrium tetragonal phase is established at room temperature. |
