  • The Symposium on Chemistry in High Temperature Aqueous Solutions was organized to afford an opportunity to bring together those interested in this topic. Those who attended included scientists and engineers who had produced research results in the field and/or developed modeling procedures for interpretation of experimental data. In addition, EPRI personnel and plant operators were in attendance. Topics presented included chemistry, data acquisition, modeling, and industrial needs and assignment of priorities. Each report will be cataloged individually. 810 refs., 212 figs., 82 tabs.
  • These proceedings discuss topics on hot corrosion high-temperature electrochemistry, sulfidation and oxidation/sulfidation, the oxidation of metals, the oxidation of ceramics, reactive-element effect, the role of grain boundaries, vaporization of inorganics, electronic materials and coal combustion, and the synthesis of materials. Papers are presented on electrical conduction in molten sodium sulfate, the sulfidation of Fe-Ni alloys, the kinetics of the growth and diffusion barrier properties of rapid thermally nitrided titanium, the effects of oxygen and water vapor pressures on the oxidation of iron at 573 K, and the strength and the structure of SiC fiber after exposure to high temperature. Attentionmore » is also given to the effect of sulfur and zirconium codoping on the oxidation of NiCrAl, the high-temperature processing of superconducting YBa/sub 2/Cu/sub 3/O(6.9), applications of high-temperature chemistry to space research, the carbonitriding of titanium with a plasma jet under reduced pressure, and the use of oxidation-reduction (thermite) reactions to produce titanium diboride.« less
  • Topics discussed in this symposium include the theory on high-temperature superconductivity, materials preparation and characterization, structure-property relationships, surfaces and interfaces, processing and fabrication, applications, and research needs and opportunities. Papers are presented on valence bond theory and superconductivity; the synthesis of new classes of high-temperature superconducting materials; the interplay of the synthesis, structure, microstructure, and superconducting properties of YBa/sub 2/Cu/sub 3/O/sub 7/; superconductivity in YBa/sub 2/Cu/sub 3/O(x) for x greater than 7.0; and oxide ion vacancies, valence electrons, and superconductivity in mixed-metal oxides. Attention is also given to the comparison of the 1-2-3 phase and the 3-3-6 phase in themore » La-Ba-Cu-O superconductor series; occupied and unoccupied electronic states, surface stability, and interface formation in high-temperature superconductors; the fabrication of YBa/sub 2/Cu/sub 3/O/sub 7/ superconducting ceramics; applications of high-temperature superconductivity; and research opportunities and new directions in high-temperature superconducting materials.« less
