摘要Mn0.43Ni0.9CuFe0.67O4 nano-sized powders were synthesized by the Pechini method for the first time. A spinel-type phase was attained from calcining of the polymerized gel precursor at 400-700 °C. The thermal evolution, surface morphology, and structural behavior have been studied by TG/DTA, SEM, XRD and FT-IR. It was found that the material decomposes upon heating above 300 °C. The monoclinic structure of CuO was found to be coexistent with the spinel-type phase in both the calcined powders and the sintered ceramics. The electrical properties were deeply affected by the crystal phase of CuO. The ceramics sintered at 1100 °C showed the best electrical properties as well as the density, of which the relative density was measured to be about 96%. The resistivity ρ25 °C is about 600 Ω cm and B25 °C/50 °C is about 2000.
