Temperature dependence of elastic properties for MgO

Serizawa, Hiroyuki ; Fukuhara, Mikio*; Nakajima, Kunihisa ; Iwai, Takashi; Arai, Yasuo

Longitudinal and transverse wave velocities, five kinds of elastic moduli, Debye temperature and Gruneisen parameter have been simultaneously measured as functions of temperature from 298 to 1764 K in polycrystalline MgO, by help of aluminum couplant. Young, shear, bulk moduli, and Gruneisen parameter and Poisson's ratio decreased and increased monotonically with increasing temperature, respectively, showing a lowering of ionic bonding strength. Lame parameter versus temperature slope is almost zeroing in the whale temperature region. The behavior was interpreted as an interlocking associated with network of short Mg-O bonds, based on three-dimensional volume-nonpreserving shear.
