Paper Abstract

The shock compression behavior of LiF has not been well studied in the pressure region between several and several 10s of GPa. In this study, the Hugoniot-measurements experiments were performed on a LiF single crystal for the <100> and <110> axis orientations in such pressure region by means of the inclined-mirror method combined with a powder gas. As a result, anisotropic Hugoniot-compression behaviors were observed. The shock front profiles showed an anomalous multi-wave structure, which were consistent with the VISAR measurements. The final Hugoniot points along the <100> axis roughly coincided with the static compression curve, but, those along the <110> axis were situated in the higher stress region than those of the <100> axis and converged to them at up to 15 GPa. The Hugoniot data in the higher pressure region coincide with those obtained by the flash-gap method.
