Answer to Question #120682 in Inorganic Chemistry for Yuki

Question

Which structure types are particularly suitable for superionic conduction?

Answer 1

The structural features of the superionic conductors include: small ion size, low ion charge, low coordination number for mobile ions, large number of vacant sites, rigid framework with open channels or layers where ions can migrate.

The superionic compounds can be divided into two big groups based on the studies of the widely studied compounds - AgI and beta-PbF₂. The most common include perovskite-structured oxides and Li⁺ containing spinel-structured compounds.
