Application of NTC (Negative Temperature Coefficient) material in preparation of electrode material
The invention belongs to the technical field of thermal sensitive ceramic materials, and discloses application of an NTC (Negative Temperature Coefficient) material in preparation of an electrode material. The NTC material is MnaCobNicFedAl1-a-b-c-dO4, a is larger than or equal to 0.50 and smaller than or equal to 0.55, b is larger than or equal to 0.060 and smaller than or equal to 0.065, c is larger than or equal to 0.20 and smaller than or equal to 0.25, and d is larger than or equal to 0.025 and smaller than or equal to 0.030. The NTC material is used for preparing a gold electrode material and a silver electrode material, the two electrode materials both have excellent electrical properties, and the R-T table average deviation from a 1K/4537 product is very small; in addition, the two electrode materials also have excellent high-temperature stability, and after the two electrode materials are aged at 300 DEG C for 1000 hours, the change rates of R25 and B100/200 are very small; the NTC material disclosed by the invention is proper in element type and proportion, simple in preparation process, low in cost and good in reproducibility, and lays a foundation for wide application of the NTC material.
本发明属于热敏陶瓷材料技术领域，本发明公开了一种NTC材料在制备电极材料中的应用。该NTC材料为MnaCobNicFedAl1‑a‑b‑c‑dO4，0.50≤a≤0.55，0.060≤b≤0.065，0.20≤c≤0.25，0.025≤d≤0.030。将所述NTC材料用于制备金电极材料和银电极材料，两种电极材料均具有优异的电性能，与1K/4537产品的R‑T表均偏差很小；此外，两种电极材料还具有优异的高温稳定性，在300℃下老化1000h后，R25和B100/200变化率均很小；本发明NTC材料所含元素种类以及比例恰当，制备工艺简单，成本低，具有很好的重现性，为NTC材料的广泛应用奠定了基础。
