Abstract

Accurate measurements of the longitudinal and shear velocities, densities, elastic constants, and lattice constants of two sapphire single-crystal ingots grown by the Bagdasarov method and the Kyropulos method are reported. No significant differences were observed in the acoustic properties of the two crystals. The elastic constants and densities were accurately determined, with considerable differences in c₁₃, c₁₄, and c₃₃, as compared with the published constants, and the sign of c₁₄ was confirmed to be positive.
