N2 - Elastic modulus measurment of ceramics up to 1000°C was made practicable by improving the peizoelectric composite-bar method. The piezoelectric vibrators were made from an LiNbO3 single crystal with the Curie temperature as high as 1210°C. The effective piezoelectric constants of the LiNbO3 crystal were analyzed, and then the cutting direction which yields pure longitudinal vibration was determined. The present method was applied to measuring the Young's modulus E and the internal friction Q-1 of 2Y-TZP with the dimension of 1 × 2 × 12 mm, and anomalous behavior in E and Q-1 was observed at ca. 300°C.
