The work is devoted to the investigation of the electrophysical properties of nanopowder systems based on zirconia in a compacted form with varying degree of system hydration. The dependence of conductivity and activation energy of conductivity on the amount of moisture in the system was studied. It is shown that the value of the total impedance of the system decreases by 55 times as the amount of moisture in the system increases from minimum to maximum. The main contribution to conductivity is made by diffusion processes in the space between nanoparticles. The possibility of using this effect to characterize the thermodynamic environmental conditions, in which the system is located, is shown.
