Semiconductor ceramic having negative resistance/temperature characteristics and semiconductor ceramic component utilizing the same

摘要

There is provided a semiconductor ceramic having negative resistance/temperature characteristics constituted by a YCaMn type oxide ceramic expressed by the formula Y_1-xCa_xMnO₃ (x = 0.2 to 0.6). Further, there is provided a semiconductor ceramic component including a ceramic body having negative resistance/temperature characteristics and electrodes formed on the ceramic body. The ceramic body is made of a YCaMn type oxide ceramic expressed by the formula Y_1-xCa_xMnO₃ (x = 0.2 to 0.6).
