Abstract:
A barium titanate-based semiconducting ceramic, comprising BaTiO.sub.3 as a main component and Ba.sub.2 TiSi.sub.2 O.sub.8 and Ba.sub.n Ti.sub.m O.sub.n+2m (1.ltoreq.n.ltoreq.4, 2.ltoreq.m.ltoreq.13, n.ltoreq.m), respectively, as trace-phase compositions, wherein a ratio of the contents of Ba.sub.2 TiSi.sub.2 O.sub.8 and Ba.sub.n Ti.sub.m O.sub.n+2m as the trace-phase compositions (Ba.sub.2 TiSi.sub.2 O.sub.8 /Ba.sub.n Ti.sub.m O.sub.n+2m) is in the range of about 0.5 to 80.0.
