A generalized scientific review with elements of additions and clarifications has been carried out on the methods theoretical research electrophysical properties crystals ionic–molecular chemical bonds (CIMBs). The main tools adopted are quasi-classical kinetic theory as applied to ionic subsystems relaxing in layered dielectrics (natural silicates, crystal hydrates, various types ceramics, perovskites) an electric field. universal (applicable for any CIMBs class crystals) nonlinear equation practical importance constructed. This describes, complex Poisson equation, mechanism ion-relaxation polarization conductivity a wide range polarizing field parameters (0.1–1000 MV/m) temperatures (1–1550 K). physical model is based system non-interacting ions (due low concentration crystal) moving one-dimensional, spatially periodic crystalline potential field, perturbed by external energy spectrum assumed be continuous.
