    摘要： Materials systems resistant to penetration of molten salts and may be present within a molten-salt-facing wall of a device for containing a molten salt bath at an elevated temperature, and molten-salt-facing walls and devices formed by such materials systems. A first layer of such a system defines an outer surface for direct contact with the molten salt bath, and resists erosion and corrosion and is penetrable by the molten salt at the elevated temperature. A second layer is located adjacent to the first layer and exhibits little or no wetting by the molten salt so that at least a portion of a thickness of the second layer is not penetrable by the molten salt. A third layer is located adjacent to the second layer and is porous and exhibits a low thermal conductivity at the elevated temperature.

    摘要： Methods for producing final bodies that contain a fine-grained refractory complex concentrated alloy (RCCA), as well as RCCAs, intermediate materials and final bodies containing the RCCAs, and high-temperature devices formed by such final bodies. Such a method includes providing a precursor with one or more precursor compounds containing elements of an RCCA, reducing the precursor compounds in the precursor via reaction with a reducing agent so as to generate the RCCA and a compound comprising a product of the reaction between the reducing agent and the precursor compounds, generating a solid material that contains at least the RCCA, forming with the solid material a porous intermediate body, and consolidating the porous intermediate body so as to partially or completely remove the pore volume from the porous intermediate body, and in doing so yield either a denser final body or a denser film.
