Anion conductors chalcogenides

A table of ionic conductors that behave in a similar way to a-Agl is given in Table 5.4. Some of these structures are based on a close-packed array of anions and this is noted in the table the conducting mechanism in these compounds is similar to that in a-Agl. The chalcogenide structures, such as silver sulfide and selenide, tend to demonstrate electronic conductivity as well as ionic, although this can be quite useful in an electrode material as opposed to an electrolyte.
