Title: | Metal-Oxide Debye Temperature's and Elastic Constants: Estimation From Interionic Spacing |

Published: | January 01, 2001 |

Abstract: | For cubic metal oxides, we show relationships between crystal-structure-volume properties and elastic-stiffness properties. The interionic distance (or the crystal structure plus volume) gives the bulk modulus B. The product of effective atomic mass and atomic volume gives the Debye temperature θ_{D}, which gives the shear modulus G. From B and G, we estimate other elastic constants such as Young modulus E and Poisson ratio υ. We apply this approach to twenty-three cubic metal oxides where there exists crystal-structure information, but no elastic-contant information. To develop the relationships, we consider elastic and related properties of seventeen cubic oxides. |
