| 英文摘要 | The NTC thermistor nano-powders of Mn1.05-yCo 1.95-x-z- wNixMgyAlzFewO 4 were prepared by microemulsion method. Scanning electron microscope (SEM) image showed that the particles were well distributed. The mean particle-size was 72 nm. The structure of the precursor was investigated with Fourier infrared spectrometer (FI). The compositions of the powder and the as-sintered ceramic were evaluated by Energy Disperse Spectroscopy (EDS). X-ray diffraction (XRD) result indicated that the sintered samples were in the spinel structure. The room temperature resistivity ρ25, material constant B25/85 and activation energies of the NTC thermistor are in the range of 1173-19,059 Ω cm, 3169-3771 k, 0.2672-0.3136 eV. The room temperature resistivity and B25/85 constant were found to increase with Al2O3 content. The Mn0.9Co 1.2Ni0.21Mg0.15Al0.09Fe 0.45(A2) and Mn0.9Co1.2Ni0.27Mg 0.15Al0.03Fe0.45(A3) specimens both showed a 200 C resistance drift (ΔR/R) within 10% after aging at 910 C for 600 h. |
