The prepared experimental samples were chracterized by electrical measurements. A comprehensive study of electrophysical properties of thermosensitive semiconductor ceramics Cu0.1Ni0.8Co0.2Mn1.9O4, synthesized under different duration of isothermal sintering and cooling regimes. The grain-porous structure of these ceramics was investigated by positron anhihilation spectroscopy. A comprehensive study of chemically-modified spinel nanoporous dielectric ceramics was performed using positron anihilation spectroscopy technique. A general model of positron annihilation in humidity-sensitive ceramics is developed.
