Abstract
In this paper an attempt has been made to trace the relation between the sintered microstructure and electrical properties of a NTC thermistor (Negative Temperature Coefficient) in the Mn-Co-Ni system. The results indicate that the electrical resistivity and B constant increase as the sintering temperature increases, but porosity decreases. Various sintering parameters are also reported. Also considered was the possibility of a fuel level sensor application using the above mentioned material.

Keywords: NTC (Negative Temperature Coefficient), fuel level sensor, thermistor, B constant
