Pressure Calibration for Multi-Anvil Apparatuses in High-Pressure Eatrth Science

Abstract

Accurate characterization of the pressure and temperature environment in high-pressure apparatuses is of essential importance when we apply laboratory data to the study of the Earth's interior. Difficulties in pressure determination of multi-anvil apparatuses are summarized. The First International Pressure Calibration Workshop is briefly reported with the Preliminary International Pressure Scale (PIPS-97). Some prospects on the pressure scale at high-temperatures for the multi-anvil apparatuses are discussed.
