Summary The isothermal p-V relation for Al2O3 at 295 °K is established by using a polynomial quadratic in p to represent the isothermal bulk modulus, B T, as a function of pressure. The second order derivative of B T with respect to pressure at p=0 is evaluated from available ultrasonic data. Comparison between experimental compression measurements and the present calculated results shows excellent agreement up to at least 1 megabar. It also shows that there seems to exist a phase transition in the neighborhood of 1.3 megabars. The pressure variations of the Grüneisen parameter, the volume coefficient of thermal expansion, and the specific heats are also investigated in the range from 0 to 150 kilobar. It is found that these properties decrease with increasing pressure.
