Crystallographic form

WebClassification of crystallographic defects ( microscopic defects) is frequently made according to the geometry or dimensionality of the defect. Other macroscopic defects exist in all solid materials that are much larger than microscopic, these include pores, cracks, foreign inclusions, and other phases. Point Defects. WebDec 13, 2024 · For simple crystallographic forms, which generate polyhedra characterized by topological variety, it is proposed to use the algorithm for calculating generalized polyhedra; using the latter, one can estimate the dissymmetrizing effect of environmental factors on a dissolving (or growing) crystal.
