WebTherefore, the search for the new materials with complex properties such as high oxygen-ion conductivity and corrosion resistance in halide melts is extremely important. As follows from the work [ 35 ], the pyrochlore Gd 2 Zr 2 O 7 is a promising compound for its further modification and investigation in the molten salts. WebA well-known ion conductive solid is β''-alumina ("BASE"), a form of aluminium oxide that has channels through which sodium cations can hop. When this ceramic is complexed with a mobile ion, such as Na +, it behaves as so-called fast ion conductor. BASE is used as a membrane in several types of molten salt electrochemical cell. [2]
