Aging processes in the two types of temperature-sensitive Cu 0.1 Ni 0.8 Co 0.2 Mn 1.9 O 4  ceramics (two-phase and with different amount of NiO phase) as well as thick films base on Cu 0.1 Ni 0.1 Co 1.6 Mn 1.2 O 4  ceramics were investigated. It is shown for Cu 0.1 Ni 0.8 Co 0.2 Mn 1.9 O 4  ceramics prepared at 1170 °C with addition treatment at 850 °C that the post-separation process of the second phase continue under heat at temperatures of 125 and 170 °C. It has been found that higher thermal aging leads to more pronounced changes in electrical resistance. Addition temperature influences contribute to the stabilization of ceramic parameters. The aging test at 170 °C results in a 7.5% reduction in electrical resistance, while at 125 °C this value is only 6%. It is shown that NiO phase additives formed during sintering of Cu 0.1 Ni 0.1 Co 1.6 Mn 1.2 O 4  ceramics and located near the grain boundaries of ceramics inhibit the aging process in these materials. This effect is characteristic of fine-grained ceramics obtained by thermal energy converted during sintering. It is established that the kinetics of aging in Cu 0.1 Ni 0.1 Co 1.6 Mn 1.2 O 4  ceramics is described by the relaxation function of DeBast-Gillard or Williams-Watts, regardless of the composition of the ceramics. The aging kinetics in thick films based on Cu 0.1 Ni 0.1 Co 1.6 Mn 1.2 O 4  ceramics at 170 °C is also adequately described by the compression-exponential relaxation function.
