The review of the theoretical study of the critical phonon scattering and anomalous heat transport near the phase transition temperature $T_{\mathrm{c}}$ is presented. An interpretation and quantitative approach to the description of the anomalous temperature dependence of the thermal conductivity $\lambda(T)$ near $T_{\mathrm{c}}$ are discussed.

Key words: ferroelectrics, phase transitions, critical phonon scattering, heat transport theory, soft-phonon mode, central peak
