摘要: 研究了SrCo1-xNixO3-δ(0≤x≤0.10)陶瓷材料(x=0,0.02,0.05和0.10)的微结构和电性能。SrCo1-xNixO3-δ陶瓷样品的结构用XRD和SEM测试分析,用热敏电阻数据采集系统测试了样品在低温-196℃和-183℃下的阻值和热敏电阻常数B值。样品的电阻值和B值随含量x的增加而增大、烧结温度的升高和恒温时间的增加而减小。测试结果表明:SrCo1-xNixO3-δ陶瓷是一种预计可在-196℃以下使用,很有应用前景的低温热敏电阻材料。
英文摘要: The microstructure and electrical properties of SrCo1-xNixO3-δ (0 [less-than or equal to] x [less-than or equal to] 0.10) ceramic were investigated (x = 0, 0.02, 0.05 and 0.10). The microstructure of SrCo1-xNixO3-δ Ceramics was studied by XRD and SEM. The electrical resistance and thermistor materials constant (B value) of samples were measured at low temperatures, such as -196°C and -183°C. The results show that the electrical resistance and the B value of samples increased with the increasing content x and decreased with the increasing sintering temperatures and the soaking time. The SrCo1-xNixO3-δ ceramics could be potentially applied at temperatures -196°C as NTC thermistor materials.
