Advances in the generation and transmission of very high frequency ultrasonic signals make it practical to measure elastic properties in single crystals small enough to be subjected to high pressures and temperatures in a new diamond anvil cell designed for simultaneous ultrasonic and x-ray diffraction measurements up to 5 GPa and 400°C. In addition to providing a new accurate method for measuring elastic properties this technique can provide simultaneous equations of state which can be used to produce a new primary pressure scale. Preliminary measurements on MgO show the feasibility of this new technique.
