| 简介 |
Provided is a semiconductor ceramic element constructed by using a semiconductor ceramic that generates metal-insulator transition at a temperature of actual use and has a sufficient strength to enable easy handling. The semiconductor ceramic element has an element main body having a semiconductor ceramic made of a perovskite-type or pyrochlore-type oxide containing a rare earth element, nickel, and titanium, in which a part of the nickel is present as metal nickel; and a pair of electrodes formed to interpose the element main body therebetween. This semiconductor ceramic element shows a sharp resistance change within a temperature range of actual use, and can be used advantageously as a temperature sensor. |
