WebThe formula for the number of imperfections in a crystal is as follows: n = N e - E d k b T. Here, n is the number of imperfections, N is the number of atomic sites per mole, E d is free energy required to form defects, k b is the Boltzmann's constant, and T is the absolute temperature. Following are the various types of point defects: WebOther imperfections in crystals involve many atoms. Twinning is a special type of grain boundary defect, in which a crystal is joined to its mirror image.
