| 英文摘要 | Negative temperature coefficient (NTC) thermistor materials based on (LaMn0.5Co0.5O3)(x)-(Ni0.66Mn2.34O4)(1-x) (0 a parts per thousand currency sign x a parts per thousand currency sign 0.5) composite ceramics, are fabricated by the conventional solid-state reaction method. The crystal structure, surface morphology and electrical properties of the composite ceramics are investigated and characterized by X-ray powders diffraction (XRD), scanning electron microscope (SEM), and Agilent digital multimeter, respectively. XRD results show that main phases of as-sintered ceramics are a cubic spinel structure Ni0.66Mn2.34O4 phase and a rhombohedral perovskite structure LaMn0.5Co0.5O3 phase. SEM images indicate that the grain size of the composite ceramics decreases with increasing the low-resistivity perovskite phase. The rho (25) and B value of the composite ceramics decreases with increasing x, and the B is still reasonably high in the range of 4000-3500 K when x a parts per thousand currency sign 0.2. Meanwhile, the introduction of the perovskite phase leads to a decrease in the resistance drift, which the Delta R/R-0 is relatively low (0.26-1.8 %) after annealing at 125 A degrees C for 600 h in air atmosphere. These findings exhibit that (LaMn0.5Co0.5O3)(x)-(Ni0.66Mn2.34O4)(1-x) (0 a parts per thousand currency sign x a parts per thousand currency sign 0.5) composite ceramics have a higher electrical stability in comparison with Ni0.66Mn2.34O4 ceramics, are helpful for meeting demands for obtaining better stability and performance of NTC composites ceramics. |
