Q6 of 26 Page 1

Name the crystal defect which reduces the density of an ionic solid? What type of ionic

substances show this defect?



• In Schottky defect the density of the ionic solid is reduced.


• Schottky defect is shown by the type of ionic substances in which the cation and anion are of almost of similar sizes i.e. value of radius differences are less.


Eg. - NaCl, KCl, CsCl and AgBr etc.
