44.	Defects which do not disturb the stoichiometry are called stochiometric defect. At the time of crystal formation an ion may not occupy its expected position leaving a void or hole at that site. As a metter of fact one positive and one negative ion are missing from their respective positions leaving behind a pair of holes. This vacancy is a Schottky defect. Due to this defect density decreases.Defect arises in which certain atoms or ions have migrated to interstitial position some distance removed from the holes which they vacated. In this case there is no change in the density of the crystal.In the Schottky defect
