摘要：

Two atomistic models are used to investigate defect structures formed when high concentrations of Al(2)O(3) are disserved in the MgO lattice. Clusters consisting of one magnesium vacancy charge compensated by either one or two substitutional ions dominate. The results compare favourably with experimental lattice parameter data.
