Abstract
The data on the goniometric study of the most common sculptures on the surface of natural diamond crystals are summarized. These sculptures consist of flat microplanes, which appear during the growth or dissolution of diamond crystals. They are a component of their surface and take an immediate part in the creation or destruction of diamond crystal faces. The results of goniometry for trigonal and ditrigonal hatchings on octahedron edges, straight- and inverse-parallel triangular and hexagonal pits on octahedron faces, quadrangular pits on cube faces, and drop-shaped hillocks and caverns on rounded dodecahedron faces are considered. It is shown that the most common microplanes of sculptures crystallographically correspond to the simple crystal forms, which often have large symbols and form clusters generally around the most important diamond structure forms.
期刊介绍：
Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
