Elastic Constants of Zircon

The elastic constants of a single crystal of zircon have been determined using the ultrasonic wedge method. The values of the constants are (units of 1011 dynes/cm2) c11 = 7.35, c33 = 4.60, c44 = 1.38, c66 = 1.60, c12 = 0.90 and c13 = −0.54. The value of compressibility β=47.6×10−13 cm2/dyne.
