WebSchottky defect is a type of point defect in which vacancies of ions occur at some points in the crystal lattice. This defect is stoichiometric in nature i.e., the stoichiometry of the crystal does not change with this defect as the number of cations and anions that are missing are equal in number.

Web(1) Yes, Schottky defects can exist in K2O; each defect will consist of one O2- vacancy and two K+ vacancies. (2) No, in the strict sense, Schottky cannot exist in K2O if we consider this type of defect to consist of a cation-anion pair; for every O2- vacancy created there must exist two K+ vacancies.
