Aluminum oxide sintered body and method for producing the same |
| abstract |
An aluminum oxide sintered body that can be adjusted to an intermediate volume resistivity between the Coulomb type and the Johnson-Rahbek type and has excellent corrosion resistance. The aluminum oxide sintered body of the present invention has a layer containing a phase containing rare earth elements and fluorine between particles of aluminum oxide as a main component, or aluminum oxide as a main component. A phase containing rare earth elements and fluorine exists along the edges of the particles. In this aluminum oxide sintered body, when a SEM image is viewed, a phase containing a rare earth element and a fluorine element is not locally present between aluminum oxide particles, but a line segment is formed. It exists as it is. The sintered aluminum oxide of the present invention has a volume resistivity of 1 × 10 13 to 1 × 10 16 Ω · cm calculated from a current value after 1 minute has passed by applying a voltage of 2 kV / mm at room temperature. Can be easily adjusted to the range. [Selection] Figure 1 |
