In this defect,cation and anion are lacking in stoichiometric proportion.

(A) In Schottky defect,cations and anions are missing from their lattice sites in stoichiometric proportion. It is a type of vacancy defect in ionic solids. To maintain electrical neutrality,the number of missing cations and anions must be equal. This defect decreases the density of the crystal.
