The Hugoniot of sapphire was measured for the first time above 145 GPa, from 80 GPa to 340 GPa in shock-wave experiments using projectiles accelerated by a two stage gas gun. The transit times of the shock waves were measured either optically with a streak camera or through electrical pin contacts. The Hugoniot in this pressure range fits U[sub s]=8.74+0.96 U[sub p] in km/s. [copyright] 1994 American Institute of Physics
