文摘

A new tetragonal phase of PbTiO₃ was discovered, in which each TiO₆ octahedron pair shares an edge and stacks over following pairs in an interlaced manner to form a one-dimensional (1D) columned structure along the c-axis. This new tetragonal phase of PbTiO₃ transforms into a normal perovskite phase in air at elevated temperature.
