In this lesson discussed about various defects and gave a detail description of point defects. Otherwise it is called zero dimensional defects. In crystals, particles are arringed in well defined manner, the deviation from this perfection leads to defects. There were point defects, one dimensional defects or line defects, two dimensional defects or surface defects, and three dimensional defects or volume defects. The various point defects are a) vacancy b)self interstitial. But in case of ceramics it is Frenkel defect and Schottky defect. Also said about one additional defect called Non-stochiometric defect.
