Thermodynamic functions E 3000Investigaton of the Thermodynamics Governing Metal Hydride Synthesis in the Molten State Process. -The molten state process provides a synthetic method for developing new high capacity, reversible hydrogen storage materials based on fusing different complex hydrides at elevated temperatures and pressures to form new species. The thermodynamics of the formation of complex hydrides such as KAlH4, NaK2AlH6, NaMgH3, Mg(AlH4)2, and Ca (AlH4)2 by the molten state process are investigated. The products are structurally characterized by XRD and their hydrogen desorption properties are tested. -(STOWE, A. C.; BERSETH, P. A.; FARRELL, T. P.; LAUGHLIN, L.; ANTON, D.; ZIDAN*, R.; J.
