The sonic resonance technique was used to determine the elastic moduli of polycrystalline Yb 2 O 3 samples of rectangular cross section ranging in pore fraction from 0.058 to 0.27 at temperatures from 25° to 1000°C. The data showed that the Young's and shear moduli are best related to pore fraction by a linear equation and to temperature by the Wachtman equation. The Debye temperature for Yb 2 O 3 was calculated from the Young's and shear moduli to be 385°K.
