The ionic polarizabilities in Pb(ZrxTi1−x)O3 compositions are calculated by the Clausius‐Mossotti‐Lorentz‐Lorentz equation. The resultant gap of the polarizability appearing at the morphotropic phase boundary (MPB) composition suggests the phase transition boundary to be due to the electrostatic long‐range dipole moment. Semiconducting and phonon softening of PZT near MPB compositions may be arrived at from screening of the long‐range dipole‐dipole interaction by electrons.
