Abstract
ⶠWe develop a mathematical model, i.e., a linear relation of ionic conductivities and the relative Coulomb's energy, to predict the ionic conductivities of oxyapatites. ⶠThe inputs to the model are two elemental properties of ionic radius and electronegativity of the constituent elements. ⶠWe study the effects of the two elemental properties on ionic conductivity. ⶠWe predict a wide range of new oxygen stoichiometric oxyapatites with ionic conductivities potentially as high as 10â2 - 10â1 S cmâ1 at 500 °C. ⶠWe suggest an optimization strategy to search for promising oxyapatites, i.e., applying dopants of large ionic radii and low electronegativities.
