Abstract :
The features of bulk acoustic wave (BAW) propagation in crystals of symmetry 3m under uniaxial pressure at room temperature were examined. Acoustic modes, cuts, and stresses directions which would be used to determine the third-order elastic constants (TOEC), have been defined. BAW phase velocities as well as their pressure dependences in basic and rotated cuts of LiTaO3 crystal have been investigated experimentally.
