| Outline of Final Research Achievements |
Aiming for an application to the high temperature pressure sensor, semiconductive ceramics foam incorporated with a narrow slit has been fabricated by the superplastically foaming method. We investigated the pressure dependence of resistance on the zinc oxide based foaming body, by changing the fabrication process and composition. The resistance of the sample decreased with an increase in pressure both at room and high temperatures. The performance of this type of sensor has been improved by doping ambivalent atoms (Ag and Li) into the matrix.
