The migration of cations with a charge greater than 1 has received very little attention historically, perhaps due to no commercially driven demand for the research as well as the common assumption that these processes will be highly hindered due to large interactions between the mobile ion and the lattice it passes through. It is the aim of this proposal to challenge those conceptions and confirm the first potential example of superionic conductivity of the Mg2+ ion through a crystalline lattice. It is hoped this research will stimulate others in the defect chemistry community to reconsider how multivalent ions migrate through solids, to obtain a better understanding of this phenomena.
