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.
