Abstract
Ab initio calculations allow to distinguish boron atoms in BO3 and BO4 complexes in lithium borates. On this basis an effective potential model for single crystals of Li2O-B2O 3 is suggested. Empirical parameters of the interaction potentials are optimized in order to reproduce the experimental data of lithium tetraborate. The optimized parameters are applied to calculations of the structures of the anhydrous borate single crystals Li3BO 3, LiBO2, Li2B4O7, Li3B7O12 and LiB3O5. The range of applicability of the potential model is increased by introducing a dependence of the effective oxygen charges on the Li content. In this way good agreement with experimental data is obtained for calculated structural and elastic properties.
