A model describing dielectric properties of the system of high-disperse fuel-containing lava-like materials (FCLM) with dipole particles adsorbed onto their surface is proposed. These dipole particles are in equilibrium with the environment, so the process of their adsorption is affected by the range of factors. Main dielectric properties of the system described by such a model are obtained in the mean field approximation and their dependences on external electric field, chemical potential of dipole particles and temperature are studied. The model proposed allows one to calculate average occupancy, spontaneous polarization and static dielectric susceptibility for pieces of FCLM with various shapes.
