采用氧化物固相法制备Mn_(2.25-x)Ni_(0.750Co_xO_4(0.8≤x≤1.2)系列NTC(negative temperature coefficient)热敏电阻粉体材料.利用激光粒度分析、XRD、SEM和电性能测试等手段,表征了煅烧材料的颗粒尺寸、陶瓷体的物相、形貌以及陶瓷材料的电学特性与Co含量的关系.结果表明:在1130~1230℃烧结温度范围内,该材料体系的B值和电阻率ρ25℃随Co含量的变化范围分别为3487~4455 K和1998~203617Ω·cm,B值和电阻率随Co含量的增加先增大后减小.该材料系列电阻率和B值调整范围较大,是一种具有实际应用价值的NTC热敏电阻。 |

A series of composite of the negative temperature coefficient(NTC)powders of Mn_(2.25-x)Ni_(0.750Co_xO_4(0.8≤ x≤1.2)materials were prepared via solid-state method.The particle size of calcined powders,ceramics phase structure,morphology and electrical properties were characterized by laser particle size analyzer,XRD,SEM and electrical measurements,respectively.The results show that when the Mn_(2.25-x)Ni_(0.750Co_xO_4 ceramics sintered at 1130~1230℃,their characteristic parameters B25/50 value are found to be in the range of 3487K to 4455K and their electrical resistivitiesρ25℃are 1998-·cm to 203617Ω·cm.The B25/50 value andρ25℃first increases and then decreases as the Co content increases.This means that electrical resistivity and B value of Mn_(2.25-x)Ni_(0.750Co_xO_4 ceramics could be adjusted to the desired values and this ternary system can be considered as the advanced semi-conducting materials for NTC thermistor applications. |
