Abstract
The influence of synthesis parameters, such as calcination temperature and sintering temperature, on the microstructure, phase composition, and electrical properties of NiMn2O4 negative temperature coefficient (NTC) ceramics was systematically investigated. The NiMn2O4 NTC ceramics were synthesized via solid-state coordination reaction. With increasing sintering temperatures, the relative density increased, whereas the porosity decreased. Single-phase, cubic spinel ceramic was obtained following sintering at 900 and 1,050 °C, whereas a secondary phase, i.e., NiO, was detected when the sintering temperature was higher than 1,100 °C. High-density ceramics were obtained when the sintering temperature was higher than 1,100 °C, and featured the lowest room temperature resistivity of 2,924 Ω cm and thermal constant B of 3,429 K. The latter parameter reflects the temperature sensitivity of the NTC ceramics. Variations of the electrical property were because of increases in density and onset of decomposition.
