초록

For the fabrication of semiconducting BaTiO3 ceramics at lower sintering temperature BN was selected as a sintering aid and the microsturcture of semiconducting BaTiO3 ceramics and PTCR characteristics by their microstructural changes were investigated. by adding BN to 0.1 mol% Sb2O3-doped BaTiO3 ceramics the sintering temperature showing semiconducting BaTiO3 ceramics was reduced by 16$0^{\circ}C$ from 130$0^{\circ}C$ to 114$0^{\circ}C$ and the specific resistivity ratio was increased as the amount of BN was increased.
