Abstract
The elastic and elastooptical constants of berillium hexaaluminate BeA l6O10 (BeO . 3Al(2)O(3)), a new orthorombic crystal of the berillium a luminate (nBeO . mAl(2)O(3)) family, are determined by the method of l ight diffraction by ultrasound. The elastic constants obtained are use d to calculate a number of important parameters, such as shear modulus , the modulus of volume elasticity, Young's modulus, Poisson's ratio, and the Debye temperature. The experimental and calculated data are co mpared with similar parameters for a sapphire Al2O3 crystal.
