The defect arises when equal number of cations and anions are missing from the lattice is
called Schottky defect. It is a common defect in ionic compounds of high coordination number
where both cations and anions are of the same size.
examples : KCl, NaCl, KBr etc.
Due to this defect density of crystal decreases.

A Schottky defect is a type of point defect in a crystal lattice named after Walter H. Schottky. In non-ionic crystals it means a lattice vacancy defect. In ionic crystals, the defect forms when oppositely charged ions leave their lattice sites, creating vacancies.
