Ceramics has been excellent mechanical and thermal properties. These characteristics are noticed recently and ceramics is utilized as structural materials for a heat resistant material. The knowledge of the behavior in the high temperature of grain boundary layer including sintered additive is necessary, on using ceramics as a heat resistant material. In this study, internal friction characteristic of three kinds of ceramics, i.e., the silicon nitride, the silicon carbide and the zirconia is investigated. The measurement is conducted from the room temperature to 1000℃ by an inverted torsion pendulum testing equipment. The result shows the internal friction value of the zirconia and silicon nitride has a peak. However, a peak didn't appear in the silicon carbide.
