By the method of electrochemical impedance spectroscopy the behavior of a dispersed system based on zirconia nanoparticles after exposure by high hydrostatic pressure was studied. It is established that high pressure initiates a long-term nonmonotonic process of structural relaxation, accompanied by a decrease in electrical conductivity. It is shown that the process consists of at least two stages differing in nature and rate of change in resistance.
