Abstract

Ultrasonic techniques for multi-anvil high-pressure apparatus are adapted for use in a DIA-type cubic-anvil apparatus (SAM 85) and installed on the superconducing wiggler beamline (X17B) at the National Synchrotron Light Source of the Brookhaven National Laboratory. Sound wave velocities and lattice parameters have been measured on samples of polycrystalline alumina (GE Lucalox and Coors 998) to simultaneous pressures of 9 GPa and 800 K.
