Crystals are commonly recognized, macroscopically, by their shape, consisting of flat faces with sharp angles. These shape characteristics are not necessary for a crystal—a crystal is scientifically defined by its microscopic atomic arrangement, not its macroscopic shape—but the characteristic macroscopic shape is often present and easy to see. 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.
