초록

(Ba0.8. Sr0.2) $TiO_3$ semiconducting ceramic with and without Ti-excess composition were prepared by various sintering temperature. The effects of Ti compositions on the samples were discussed in terms of color micro-structure resistivity at room temperature and the positive temperature coefficient resistivity(PTCR). The 1.02mol Ti-excess composition provides better PTCR properties and has uniform micrositructures with 5-7${\mu}{\textrm}{m}$.
