Investigation of mechanical properties of alkaline-earth oxides. I. Cohesive energy function

  • A. A. Vaal


An analysis of several calculations of the physical properties of ionic crystals and of the experimental data on the elastic moduli of alkaline-earth oxides is used to propose a semiempirical cohesive energy function, which includes not only the pair interactions of ions described by the Born-Mayer potential, but also three-body interactions. The parameters of the cohesive energy function are determined for these crystals by fitting to the experimental values of the binding energies, lattice constants, and second-order elastic moduli.
