Abstract

Thermistor is the semiconducting material whose electrical resistance is varied with its self heating. In this paper, the improvement of resistance-temperature characteristics of NTC thermistor devices based on NiO was experimented. The specimens were prepared by mixing NiO and Mn$_2$O$_3$(1:1 mole %) and by addition of CuO(1 wt %, 2 wt %, 4 wt %). The specimens were compacted at the pressure of 1000 kg/$\textrm{cm}^2$ and sintered for 1 hour in air ambient at 120$0^{\circ}C$. Reducing CuO additions not only resistance-temperature characteristics, but also increased room temperature resistance.
