Elastic moduli of spodumene crystal at pressures up to 2,0 Gpa
The velocities of longitudinal and transverse waves in the six inequivalent crystallographic directions and also the density for spodumene crystal was studied by ultrasonic impulse method in a modified solid-phase installation of high quasihydrostatic pressure up to 2.0 GPa. For samples of spodumene crystal which are oriented with crystallophysical axes the two velocities of transverse waves was obtained during their propagation along each of directions (for different directions of displacement in the wave).
