Electrical conductivities of shock-compressed solutions of KI in organic solvents

Abstract

We have measured the electrical conductivities of solutions of KI in methanol, formamide, N-methylformamide (NMF), N,N-dimethylformamide (DMF), dimethylsulphoxide (DMSO) and acetone, under compression by shock waves with pressures of the order of 10 GPa. The results indicate that acetone and NMF become more viscous in the shocked state and the DMF and DMSO become very much more so. The shock-wave conductivities of formamide, NMF, DMF and DMSO are consistent with static conductivities measured at much lower pressures.

Transparency experiments showed no evidence of freezing in DMF and acetone at shock pressures between 1 and 10 GPa.
