ABSTRACT

Mn-Co-Ni oxide system has been used as the NTC thermistors for normal temperature applications. Mn-Co-Ni oxide-based thermistors were sintered at different temperatures for a constant processing time from 900 to 1300 o C for 3 h. The crystal structure, bulk density, microstructure and chemical composition were characterized by XRD, FE-SEM and WD-XRF. The plot of the resistance versus measuring temperature was characterized for the sintered sample at the 1250 o C. Moreover, the relationship between log resistivity and reciprocal of absolute temperature of the NTC thermistor was investigated.
