摘要：
Detailed data are presented on the crystal structure of ferroelectric lead titanate ceramics produced by cold pressing at 1.2–7.0 GPa. The displacement of the Ti ions is shown to decrease with increasing compacting pressure. In addition, increasing the compacting pressure reduces the tetragonal distortion of the PbTiO3 lattice, increases the distortion of the TiO6 tetrahedra, and lowers the ferroelectric transition temperature of the ceramics.
