Porous BaTiO3-based ceramics containing potato-starch (0–15 wt.%) were prepared by wet mixing and the effect of high-energy ball-milling time (1–20 h) on the electrical property and microstructure of the porous ceramics has been investigated. With increasing potato-starch content and ball-milling time, the porosity of the BaTiO3-based ceramics containing potato-starch increased and decreased, respectively. The grain size decreased and increased, with increasing potato-starch content and ball-milling time, respectively. The room-temperature electrical resistivity of the porous ceramics slightly increased with increasing potato-starch content, and decreased with increasing ball-milling time. PTCR jump of the porous ceramic was slightly increased with increasing potato-starch content, while it was slightly decreased with increasing ball-milling time.
