Recent Studies on Ultrasonic Measurements under High Pressure and a New Analytical Methodology for Ultrasonic Velocity Data at Simultaneous High Pressure and High Temperature

Research output: Contribution to journalArticle

Abstract

Basic techniques for ultrasonic measurements are discussed with emphasis placed on accuracy of sound velocity. Recent ultrasonic studies under high pressure are briefly reviewed, and a new analytical methodology called the complete thermodynamic equation of state is introduced. The potential of the method is demonstrated by analyzing a synthetic model data set. The results suggest that the method can be used to constrain thermodynamic parameters, such as heat capacity and thermal expansivity, up to pressures of the core-mantle boundary using experimental data collected only up to 10 Gpa.
