CRYSTAL DEFECTS BY CH.PAVAN TEJA
DEFINITION OF THE CRYSTAL crystal defect, imperfection in the regular geometrical arrangement of the atoms in a crystalline solid. These imperfections result from deformation of the solid, rapid cooling from high temperature, or high-energy radiation (X- rays or neutrons) striking the solid. Located at single points, along lines, or on whole surfaces in the solid, these defects influence its mechanical, electrical, and optical behaviour.
CRYSTALS KEY POINTS Here are some key features of crystals: All big crystals are found to have some defects in the arrangement of constituent particles. The defects are more if the process of crystallization occurs at a faster rate. ... The defects are produced by irregularities in the arrangement of constituent particles. The crystal defects change the original physical and chemical properties of the crystalline solids ..
