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