Curved surfaces upon dissolution as a manifestation of physicochemical properties of crystal structure

Abstract

The curved surfaces of natural diamond are described by central second-order surfaces: a pair of planes, an elliptical cylinder, and a triaxial ellipsoid. The curved form of the elementary surface area of diamond maps the characteristic surface of the second-rank tensor, which describes the stability of the chemical bonds of atoms on an arbitrary crystal surface during normal dissolution. Diagrams of diamond forms are proposed for the descriptive presentation of the crystal form.
