| 简介 |
Provided is a barium titanate-based semiconductor ceramic composition which contains no Pb, which can have an increased Curie temperature, which exhibits slight deterioration with time, and which has high reliability, containing a barium titanate-based semiconductor ceramic represented by the composition formula (Ba1-x-y-zSry(A1Bi)xA2z)TiO3, where A1 is an alkali metal element, A2 is a rare-earth element, 0.03≦x≦0.20, 0.02≦y≦0.20, and 0.0005≦z≦0.015, and x−0.10≦y≦(5/4)·x. In addition, 0.01 to 0.20 molar parts of Mn per 100 molar parts of Ti is preferably added thereto. |
