Equation-of-state (EOS) standard materials are required for all static and dynamic high-pressure experiments. It is proposed that Al is an excellent candidate as an EOS standard, because of its simple s-p electronic structure. It can be both double-shocked and isentropically released to reach states off the Hugoniot. Its shock impedance is closely matched to that of LiF, a high-pressure window material. Double-shock experiments on Al gave agreement between effective Grueneisen parameters and constant ..gamma../V scaling at lower pressures. A shock impedance match was performed with Mo and Al in close proximity to an underground nuclear explosion. (DLC)
