The five elastic constants of single‐crystal BeO were measured to determine their magnitude relative to those of other hexagonal materials and to enable a correlation with related properties. The pulse‐echo method was used. The stiffness constants are c 11 4.70, c 12 1.68, c 13 1.19, c 33 4.94, and c 44 1.53 × 10 12 dynes/cm 2 . These were related to the Young's, shear, and bulk moduli of polycrystalline BeO, the Debye temperature, and the repulsion term for the crystal energy.
