On the relations between structure and morphology of crystals. II

Abstract

The characteristic features of S-faces (stepped faces, i.e. faces parallel to one periodic bond chain only) are further developed. After giving some definitions, a discussion follows of the factors determining the morphological importance of S-faces. The conclusion is drawn that the development of S-faces in a particular zone can be represented by an addition scheme of indices and that an S-face is the more important, the greater the relative strength of the bonds in the periodic bond chain to which it is parallel.
