Epitaxial Overgrowth of LiKSO4 on β-K2S04 Single Crystals

Abstract

Nuc1eation of LiKS04 (LKS) crystals fram non-equimolar solutions may occur epitaxially on the surface of previously nucleated , β-KZS04 (KS) crystals. Both compounds evince a prafound hexagonal substructure, and have common topological features and similar coordination schemes. Moreover, they may be related by quantitative similarities between their translation parameters and by correspondence between their bond chains along the directions of epitaxy. The planes of epitaxy are [OO1]KS and (OOO1)LKs, and on these planes [O1O]Ks is always parallel to [O1O]LKs, with a misfit of 12.19%. Another pair of directions, [11O]KS and [100]LKs, showing a small angular misfit (0.18°), exhibit an even lower linear misfit (3.09%).
