Shock-induced melting of powder compacts of a eutectic of KCl and LiCl has been investigated in an electrochemical cell in which the eutectic serves as the electrolyte with an anode of a lithium-silicon alloy and a cathode with a mixture of FeS2, the eutectic and silicon dioxide. The cell remains inactive into low impedance electrical loads until the powder is melted either under shock pressure or upon release of pressure. Melt behavior is clearly indicated in time-resolved electrochemical voltage measurements and the degree of melt is sensitive to the starting powder density which controls the increase in temperature. The indicated electrolytic conductivity suggests that melting is not complete in either the shock or release state. Such electrochemical response measurements provide capability for direct studies of melting behavior, for determination of Gibbs potentials of reactions and their kinetics while under shock compression.
