Madelung energies and cation distributions in olivine-type structures
Published/Copyright:
August 25, 2010
Abstract
Madelung energies of 16 olivine-type structures of phosphates, silicates, borates and beryllates have been computed for varying charges in sites M(1) and M(2). Predictions on the distributions of cations in sites M(1) and M(2) made on the basis of such energy calculations, are in agreement with all the refinements published so far for structures of the olivine-type. The calculations indicate a lower Madelung energy for ordered cations. Site preferences of many elements in olivine-type structures are “predicted”.
