Research Abstract

Effect of an oxygen ionic conductive properties on the anti-Frenkel type defect equilibrium have been investigated for apatite-type lanthanum silicate. Apatite-type lanthanum silicate is found to be an ideal oxygen ionic conductor in wide oxygen partial pressure and temperature region. On the other hand, the anti-Frenkel defect concentration is strongly influenced by the substitution of neodymium to lanthanum even which components had very similar chemical properties. Based on these results, the defect equilibrium in the apatite-type lanthanoid silicate can't be understood by classical defect chemical theory.
