| ABSTRACT |
|
Effect of Sb2O3 addition on microstructure and the PTCR characteristic was investigated. The range of the Sb2O3 content and the sintering temperature showing semiconducting and PTCR characteristic, were 0.05~0.125 mol%, and over 130$0^{circ}C$, respectively. We found that PTCR characteristic, that is, room-temperature resistivity and specific resistivity ration were dependent on the microstructure. |
