Abstract

The Born-Lande equation has been used to calculate the lattice energy and bulk modulus of twenty one ionic crystals. These computations were carried out by means of a FORTRAN code, whose basic inputs are the name of crystal, the Born exponent, the number of charges and the lattice constant The lattice energies obtained are in close agreement with both the theoretical and the experimental reported values. It has been found that as the ionic radii of either the cations or anions increases the lattice energy decreases.
Simalarly, ionic crystals consisting of divalent ions have much larger lattice energies than those with monovalent ions .
