Abstract
By assuming complete ionicity, a theoretical study of structure and energetics in zirconias stabilized by the addition of Y2O3 or MgO, has been reported. The simulation was carried out using the Ewald summation technique. The results indicate that the cubic structures of these ionic crystals are metastable and they transform without an energy barrier to a pseudomonoclinic or tetragonal structure.
